Rename C:\Windows\system32\libmdd.dll (e.g. to libmdd.dll.old) may resolve the issue.
Also suggest rename (delete or move) other Intel Complier dynamic link library files in above list in C:\Windows\system32, and notify other (non-ANSYS) software vendor not to put such files in C:\Windows\system32, since different applications may need different versions Intel Complier dynamic link library.
Please also send the full output of running the "set" command from a command prompt.

I am also getting the same error "The Fluent application failed to validate the connection" and find no way to resolve it.
according to your procedure, I did not find any above named file, by following this route> C:\Windows\system32\
Please help me to resolve this error.
TIAOctober 21, 2022 at 9:09 pmAkshay BhavsarSubscriberI am a student using the student version of CFD Ansys Fluent for my Master thesis to see the behavior of turbulent flow through pipes with and without a turbulator. But After drawing geometry and meshing, it shows the following error when I try to do setup of the project: "The FLUENT application failed to validate the connection". I have tried all the solutions from the learning forum but none of those didn't work for me. I'm stuck in between my master thesis due to this error.Please help me to resolve the issue.I hope you will provide me with solutions as soon as possible.I'm attaching a screenshot of my screen for reference.Thank you so much in advance.November 10, 2022 at 7:57 pmknowles90Subscriber
I have been having this issue on my desktop for roughly a year now and can't get this fixed. My laptop never runs into this issue. On my desktop, I get to setup (after meshing), I get this error and the setup closes. I send the project to my laptop and runs fine. I have reinstalled multiple times, still same outcome.January 24, 2023 at 1:30 pmtony stackSubscriber
Check project path,the project path can only be in English,Cannot be another language,I have solved this problem.February 5, 2023 at 3:02 amJoseph LicataSubscriber
I had this issue as well. It turned out to be due to the wrong number of solver GPGPUs set. On the Fluent luancher, go to the Parallel Settings tab, and ensure that the correct number of solver GPGPUs is chosen. After doing this, Fluent was able to launch for me without issue. This is on 2023 R1.

Hi! How did you determine the right GPGPUs number?
April 25, 2023 at 3:59 pmJoseph LicataSubscriber
Assuming you have 1 dedicated graphics card, set it to 1. Unless you have a server or workstation setup with multiple GPUs, it should probably be 1. If you have no dedicated graphics card, you are probably better off setting it to 0 and using only CPU processes.
Can someone please explain how to determine the right GPGPU number?

I have the same problem and I already try all the suggestion above but still doesn't workMarch 18, 2023 at 5:05 pmrifai abSubscriberMarch 18, 2023 at 5:31 pmrifai abSubscriber
I have the same problem butApril 27, 2023 at 6:04 amMarkku NikkuSubscriber
I believe this problem has little to none todo with GPU.
I had a working version of Ansys 2021 R2, that was until I installed new version of Solidworks. This effectively caused me to have this problem.
Ansys could remedy this problem by a) adding a repair feature, which could re-install the necessary extra files to system folders, or even better b) stop using system folders altogether and install and use files only from Ansys folders.May 27, 2023 at 12:34 amArmando RosalesSubscriber
I had the same problem, solved it, in my case by changing the file path to one more direct to my computer's local C: drive and running the program as administrator.
i hope i helpedViewing 17 reply threads
