An indispensable flow modeling tool

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.

Reasons for Switching to 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.

Engineering manager review for ANSYS Fluent.

We used it for heat flow in the component, these tools really help us to idetify heat flow easily

Pros

Comprehensive physics modelling,So very helpfull.

Cons

Cost is major factor and meshing sometime not good.

Always prefer STAR-CCM+ over Ansys Fluent

(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,

Ansys Fluent - Review

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.

My Love-Hate Relationship with Ansys Fluent

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.
