### "An indispensable flow modeling tool"

July 25, 2021

4.0

When it comes to computer aided analysis tools, there are not too many solutions available in the market. Ansys has been the market leader in this domain for quite sometime now, and it has consistently been rated the best. Our organisation has derived several benefits with Ansys, and it integrates well with most of the modelling softwares and PLM platforms.

Pros

I have used Ansys Fluent for modeling fluid flows for aerospace applications. I particularly like the feature set that Ansys provides. It also has support for distributed computing architecture which has been very beneficial in meshing and processing complex one dimensional CAE problems.

Cons

There are multiple UI improvements with each product release. Keeping pace with the changes and new functionalities is a bit of a learning curve. The rendering of 3D heat maps and stress diagrams is a bit choppy with certain older generation GPUs.

Reason for choosing Ansys Fluent

When the factor of cost effectiveness was considered, there was no better tool that could check all the boxes for our use cases and platform integration requirements.

### "Best tool for CFD Simulation"

May 25, 2022

5.0

I have been utilizing ANSYS Fluent for more than 6 years. I use it to simulate various problems in the field of solar thermal energy. I am extremely satisfied with ANSYS Fluent because there are many examples available on websites and forums. In addition, there are colleagues and experts who answer to various questions that help us to analyse, create, solve and develop our model. I strongly recommend scientists and engineers use it.

Pros

ANSYS Fluent is the greatest software for Computational Fluid Dynamics simulations. It comes with a number of add-ons that are incredibly useful for product research and development. Researchers and engineers could also customize the simulation by changing the input parameters needed to solve the problem under consideration (starting by creating geometry, then generating mesh, Setup the parameters, and extract results). One of its advantages is that it provides acceptable and satisfactory outcomes that are accurate and close to the experiment.

Cons

The software is difficult and requires a lot of understanding before starting up. You would first comprehend the relevant variables in order to achieve the required result. In addition, it's open source version has very limited number of cells/nodes. On the other hand, the premium version required a high-end computer (could be costly), take significantly longer to solve the problem and achieve the desired results.

### "Always prefer STAR-CCM+ over Ansys Fluent"

January 20, 2022

2.0

(Ran out of space from above question, so continuing here) which should not be the case, as it is 2022 and opening a website for reading instructions should be the most easily available thing. 6) If there is only one or two persons who answer the questions on probably a 1000 + strong or more community on the forum, you definitely need more people who could man the ansys forum. Most of the time, the answers are actually more questions, which rather point on to 1 or 2 simple things or, a new question alltogether, making the whole process of going to the forum, quite useless. And if by any chance, the question is tricky enough, they direct to open the ticket, which takes another god knows how many days, with response that "I will get back to you soon" and this soon comes withint 1 month or so, not with answers , but with more questions. 7) Also had the privilage to get a 850£ subscription to the training page, which was such a bad design. (Why don't you hire a better UI designer?), and finding data on the same was very challenging. One also needs to write email to that lady quite often, to ask for stuff, and this should not be the case. After all , for what exactly did I pay 850£ for? The training portal, is also suppose to be self-explainatory with the new versions of pdf, however, it sometimes seems, the pdfs were never updated, and I wished again for Star-CCM+. 8) So if I have to write script, scheme is the last language I would do it with because it is not 1960.

Pros

used v19R2, did the basic CFD, however, meshing on a simple geometry such as rounded pipe, seemed like a hassle. So you tell me if there is even worth going forward.

Cons

Where do I start. 1) The customer support, is now directed to the ansys forum, which I am sure, some indians are doing a good job on it, however, its a very badly maintained source. The previous version of going to portal and looking for a pdf (assuming due to some blessing, it is available), was a better approach. If you cannot open a file, becuase someone is trying to send a snapshot, then please find it in your heart to buy a better anti-virus software. I am sure such a big company such as ansys can open an attachment, if it cant get everyone through the ticketing system, which by the way, is also not very useful, or so late, that the user, ends interest, or endures to find a new method, which does not require the crappy customer support of Fluent. I am guessing that is a win win for Ansys fluent anyways. 3) The ticketing system, never was useful, as I said, needed to couple fluent with python, for v19R2, and appraently, that feature is not made yet. These are the times I wished, my supervisors had agreed on Star-CCM+, instead of fluent. 4) If something has been discontinued, or will be discontinued, take it out from the list of radio buttons or drop down menus. It is simple software engineering basic. 5) Also, again, I wished, the customer portal, were open to more appropriate documentation when required. Putting up everything online in form of instructions manual was a bad decision. Also, i am pretty sure, you had not notice, that the website, opens slowly,

Supervisors, were not comfortable, (or perhaps didn't have the license) for Star-CCM+. My previous job had StarCCM+ and it was a thing of the dreams. I constantly wish , I had Star-CCM+ instead of Fluent

### "Why Ansys Fluent?"

February 8, 2022

5.0

I used Ansys Fluent to simulate heat exchange using a heat pipe filled with various types of nanofluids.

Pros

When the appropriate parameters are included, it aids in simulating fluid behavior. This was an excellent way to double-check the results of an experiment. Heat transfer, laminar flow, and turbulent flow can all be simulated. You can learn how to use it for minor tasks in less than two months. I particularly like the variety of data and model file extensions it supports; for example, you can import data from Excel and SolidWorks or cad files. I like how the application generates a report automatically at the end of the problem-solving process.

Cons

It's a complicated program that necessitates a great deal of knowledge before you can use it. To achieve the desired result, you must first understand the necessary parameters. It also has a high price tag, much higher than comparable applications. It also has minimal system requirements, which means you'll need a high-end laptop, which can be expensive (it can work on low specs devices, but it will take much more time to solve the problem and get the results you are seeking)

### "Ansys Fluent Review"

August 12, 2021

5.0

Ansys Fluent is a generally acceptable simulation tool for computational fluid dynamics related problems. With ability to carry out multiphysics simulations and element quality check in meshing, Fluent is my most preferred and effective tool in its class.

Pros

The efficiency of its results make Ansys Fluent the most effective tool for solving computational fluid dynamics related problems. From geometry, through meshing, physics, solution and to results, the chronological order of the workflow makes Fluent easy to use, even for beginners. The fact that a user doesn't necessarily need to fully understand the governing equations required in the setup makes the learning curve less steep. A user with a deeper understanding however, can create and modify user defined functions to suit whatever solution that may be required.

Cons

There are minimum requirements to install and run Ansys generally but at times, even those minimum requirements seem to be incapable of a ensuring a smooth run. So it is prone to crashes and may require extremely long period of time to solve some complex problems. A high end computer might be required for such. Eventhough it is easy to use, a good knowledge of physics or engineering is usually required of the user to understand some processes. Also, the solver offers the user less control of the solving process as compared to some other tools.

### "Specialized and practical simulation tool for CFD related problems"

August 30, 2022

4.0

Pros

Highly specialized algorithms for diverse geometry and calculation strategies, allowing multi-physics problems could be solved easily without over consuming your hardware resources. Helping us to save an enormous amount of time and effort in understanding and predicting complex phenomena, Ansys seems like a must-have for engineers of our era.

Cons

Being a part of the Ansys ecosystem, unlike simple academic softwares, you should at least be familiar with the system in order to fully operate their functions. But for an engineer / numerical simulation professional this should be done in no time.

### "Good option for CFD"

July 9, 2022

4.0

Pros

I have used Ansys extensively in my 3 years of journey with BAJA SAEINDIA, Ansys Fluent is one of the modules provided by ANSYS which attracts a wide range of users, from novice to experts. That is the major advantage of ANSYS when compared to its competitors, the results are also comparatively accurate up till intermediate analysis

Cons

It requires a lot of technical understanding to use Fluent, of course its a simulation software and needs knowledge, but my point is Ansys can provide a more user friendly interface to help beginners play with the tool and gain more knowledge by practice

December 29, 2022

4.0

the best out there for any flow simulations.

Pros

The data visualization on this software is one of the best in the industry right now, especially for people who are dealing with flow dynamics of external or internal flows.

Cons

The UI/UX of the software is bit cluttered and its difficult to navigate through all the functions at the same time.

### "Robust CFD Solver"

August 1, 2021

5.0

I used Fluent in the automotive and aviation industries. I have more than 7 years for the application that I have used Fluent.

Pros

Fluent has numerous options to solve various types of flow. It produces fast and accurate results. According to comparison with experimental results, CFD results satisfy the researcher most of the time.

Cons

The software does not allow the user to modify the source code. It has some features to modify some interface but is not desirable for every researcher.

Reason for choosing Ansys Fluent

FLUENT was the most popular and suggested software at that time. That played important role to prefer Fluent.

### "Ansys Fluent, a must when dealing with flows"

October 4, 2022

5.0

Ansys Fluent is a must when dealing with flows, the capability of this CFD software is impressive and combined with easy visualization of results makes this the perfect combination for any CFD analysis.

Pros

Fluent is a very complex software with various customizable parameters. Results can be very elaborate or simple. From mass, heat, and energy transfer, to temperature, velocity, and pressure gradients, Ansys provides a wide range of high value results for engineers to analyze and take educated decisions.

Cons

The complexity can be boggling for users, if the user is not educated on the subject, the adjustable variables are numerous and require previous study to make the best of simulations.

### "Excellent"

February 9, 2021

5.0

Best value for money for general usage.

Pros

I have been working on Fins of a heat exchanger lately. The thing that impressed me alot, was that i can apply the thermal as well as fluiddynamic analysis on a very wide range of materials. the long list of materials impressed me. Secondly, the simplified mesh was very easy to construct on ANSYS.

Cons

Not that easy to use. It took me a while to get used to stuff. Secondly while load testing, abaqus was more handy. even solidwork was equally good plus there was an additional advantage of easy (as well as complex) modelling.

### "Easy to use but experimental validation is necessary"

August 30, 2021

4.0

I have solved just 2D CFD problems ranging from steady state simulations to transient simulations that involved oscillating airfoils. My experience has ranged from easy/smooth for simple setups to difficult for the oscillating airfoil problems (because of UDF, described before). A lot of my peers have asked me to switch to open source platforms such as OPENFoam. However, for someone who is not researching in CFD but using it as a design tool, Fluent is way more user friendly at the cost of research level customizations to tweak problem setups.

Pros

The GUI is intuitive and there are numerous youtube videos available to get familiarized with the interface. If you are a student you can also get free access to ANSYS Forums where peers help out in setting up a CFD problem.

Cons

The user-defined functions, popularly referred to as UDF is difficult to set up especially because of the way Windows handles dependencies. The plotting/visualization interface GUI is not as intuitive as setting up the problem and solving is. For example, it took me a long time to figure out how to set up custom parameters to plot such as vorticity, even with help of youtube tutorials and videos.

### "Powerful but delicate"

March 1, 2021

5.0

I have used Fluent during bachelor course for the simulation of combustion chambers and later as part of classes. The learning curve can be quite steep at the beginning but is worth it.

Pros

Extremely powerful simulation software, their expansion has led to the acquisition of several competitors and resulted in a set of simulation packages that can solve most types of problems

Cons

The license cost can be quite expensive, and the simulation has to be very carefully configured to generate a proper result.

December 13, 2022

5.0

I personally loved using the ANSYS Fluent software. The results can be obtained in the required formats.Conclusions can be easily made from the thermal contours.

Pros

The software has different working modules for battery packs. Another thing I like about using ANSYS is, it simulates the battery performance both, over the molecular and module level.One can simulate battery/battery packs over a wide range of drive cycles (Even custom drive cycle inputs are available)

Cons

The simulation consumes a lot of time and hardware RAM to provide results. (Post-processing time)

### "Ansys Fluent: thermo-fluid dynamic simulations within reach of (almost) everyone"

August 15, 2022

5.0

My experience with Ansys Fluent is very positive. In particular, I used it during the PhD path mainly for the shape optimization of the cardiac bypass. It responded very well to the parametric study and I did not find it difficult to integrate with other software. Thanks to its ease of use it allows a fast progress of the works, which allowed me to publish several scientific-numerical papers. It is also excellent for newcomers to simulations because, even if you are not very well prepared on the fluid dynamics and / or thermal theory, you can get relevant results.

Pros

The software, in the Workbench functionality, allows to decide the type of module to use depending on the physics to be solved. In particular, among the different choices for the fluid dynamics part, there is Fluent, a Finite Volume solver. It is very intuitive to import external CADs into the geometry module and prepare the mesh accordingly. The internal CAD is also very functional and, for complex components, it is useful for cleaning geometry. The preparation of the solver is also very intuitive. The tree diagram allows to not make mistakes. Very good package for displaying the results data, which is intuitive and easy to use. Among the best features that have been implemented in the latest versions is the "Named Function": a tool inside the solver part that allows to define mathematical functions, and much more, in order to bypass the use of UDFs which is always a bit difficult and not easy to understand. Exporting data is very easy since you prefer to use another software viewer or perform numeric post-processing operations with Matlab as an example.

Cons

The hardest part of the program is the definition of the mesh. if you work with simple geometries you will not encounter particular problems, but since you want to use polygonal meshes for complex geometries, you have to use another package that integrates the mesh with the solver in a different way. The use of different packages for the management of the single parts makes the program heavy, which is slow in the opening and closing phases of the single packages. Another slightly critical point is the definition of the parameters. It is not easy to understand and you have to manage them through the Workbanch. This is not a particular problem once you are familiar with the program.

### "Ansys Fluent: A Reliable Tool"

March 31, 2023

4.0

Overall, I would highly recommend Ansys Fluent to anyone in need of a powerful, reliable simulation software. Its complete documentation and well-described equations make it a valuable asset for any project, especially those involving multiphase flow simulation or critical flow of gas through tight restrictions.Despite these limitations, I still believe that Ansys Fluent is a valuable tool for simulating complex systems. Its reliability and versatility make it a valuable asset for engineers, researchers, and scientists working in a variety of fields. However, it's important to be aware of its limitations and potential challenges in order to make the most of the software's capabilities.

Pros

I have been using Ansys Fluent for some time now, and I am very impressed with its capabilities. As someone who regularly deals with multiphase flow simulation and critical flow of gas through tight restriction, I have found this software to be particularly useful.One of the things I appreciate most about Ansys Fluent is its reliability. The software has consistently delivered accurate results for a variety of complex simulations. Additionally, the documentation is complete with well-described equations, which has made it easy to set up and solve even the most challenging problems.Ansys Fluent is especially helpful for simulating multiphase flows, such as gas-liquid interactions, and for modeling critical flow of gas through tight restrictions. It allows for accurate modeling of these systems and provides valuable insight into their behavior and performance.Another advantage of using Ansys Fluent is its versatility. The software is capable of modeling a wide range of physical phenomena, including fluid dynamics, heat transfer, combustion, and more. This makes it a valuable tool for engineers, researchers, and scientists working in a variety of fields.

Cons

One challenge I have encountered is that errors can be confusing, with little explanation provided. When an error occurs, it can be difficult to determine what caused it, and there may be limited guidance available to help troubleshoot the issue. This can be frustrating for users who are trying to identify and fix problems in their simulations.Additionally, I have found that some of the software's features can be less intuitive than others. While Ansys Fluent is generally user-friendly, there are some aspects of the program that may require additional research or support to fully understand and utilize.

### "My Love-Hate Relationship with Ansys Fluent"

March 30, 2023

4.0

Overall, Ansys Fluent is an incredibly useful tool for simulation, but it comes with a steep learning curve. If you're willing to put in the time and effort to learn it, the results are well worth it.

Pros

As someone who used Ansys Fluent during my PhD studies for air quality, I found it to be a powerful but complicated simulation software. One of the best things about Fluent is that it allows you to create your 3D geometry using other software and save it in a format that Fluent can read, saving you the trouble of learning how to model in different software. The results provided by Fluent are excellent and provide a wealth of data for analysis, including animations and various plots.

Cons

While it has a user-friendly interface, it takes a lot of time to learn and is not very intuitive. I highly recommend trying some tutorials before diving in. Also, running complex simulations with a mesh of millions of elements requires a powerful cluster and can take a long time. The results are great, however, it's not always easy to get there. Errors often appear during the learning process, but the software has a strong community of users, open forums, and assistance to rely on.

August 5, 2023

5.0

Overall, I have been enjoying solving fluid problems using Ansys Fluent since 2019 and I would recommend this to my colleagues.

Pros

Ansys Fluent's main feature is the ability to run the simulation using GPU and CPU at the same time. Also, the model library, code, and algorithm are robust and proven in both many scientific research and practical applications.

Cons

The fact that its price is much higher than its competitor makes customers put Ansys Fluent as a second choice.

### "Best Tool for CFD Simulation"

March 20, 2022

5.0

I have been using ANSYS Fluent for 5 years so far. I use it in all my CFD simulation and I have been very satisfied with it. I definitely recommend researcher to use it if available through their institutions.

Pros

In my opinion ANSYS Fluent is the best software for CFD simulations. It has several add-ons that are extremely helpful for design and product development. It also offers engineers and researchers a lot of flexibility in terms of equations (flow, energy, and turbulence) and boundary conditions to setup the simulation as customizable as possible.

Cons

What I don't like very much about ANSYS Fluent is the file management. I have had a hard time finding the files I save specially when the software crashes. Hopefully, with the newest updates ANSYS will fix these bugs.

For general purpose... Ansys is the best... for particular and more material specific analysis ( like i designed my in composite and tested the equallent model on that) its not that accurate

Pros

Best for simpler and small scale FEM analysis... can also work for Solidworks imported mesh.. thats a plus and helpful for me

Cons

Just a bit slow.... requires more processor. But that isnt a drawback because FEM software have to calculate value on each node so in refined mesh they are compelled to require time.

January 21, 2022

3.0

Mixed. I appreciate the software's technical capability and support from customer support team has been very good, but the solver can be a real pain to run at hypersonic speeds at times if there is any amount iof divergence from primitive geometry.

Pros

The price is good and there is a good deal of physical model functionality from low to hypersonic. Significant V&V has been done. I like the Fluent AERO capability that is being rolled out to do sweeps of AoA, Mach, etc.

Cons

The software is very difficult to apply - significant amount of time needs invested in meshing. Other solvers (e.g. CDD++) are much easier to run successfully (i.e. quickly get solve an analysis). Find that other colvers are more capable numerically of running in the hypersonic regime. Fluent capability of integrating with Pointwise meshes that I receive from my customer is not great. Sometimes the technical support is good, other times can be a bit distant. Support received from other vendors is more engaged and actively trying to help (i.e. hands on).
