[P_e_a_R]

This error seems to be usual. I've already searched everywhere and can't reach a solution.

When installing application I've faced a problem related to the prerequisites (failed to install). I've installed one by one manually but the Ansys app wouldn't load. I've managed to change some .dll files, following a procedure find on the internet and everything went well with static structural.

But now, starting a Fluent project, I got the error: Fluent application failed to start.

I've already re-installed Ansys, turned off Firewall, re-installed prerequisites as administrator, tried to run Fluent standalone, but without success.

Can someone point me a direction to solve this?

Thanks in advance.

When you run Fluent Standalone, do you receive an error in the output window?
If so, can you post the output window window?

[P_e_a_R]

thanks for your input in this subject.

When I try to launch the app from the laucher, thats the error (missing .dll) I get!

Does this help?

Thanks

check the size of the downloaded installation file to verify that it is the same as on the download site.
That dll file should exist in 3 places:
C:\Program Files\ANSYS Inc\ANSYS Student\v212\fluent\ntbin\win64
C:\Program Files\ANSYS Inc\ANSYS Student\v212\commonfiles\fluids\lib-hdf18\winx64
C:\Program Files\ANSYS Inc\ANSYS Student\v212\commonfiles\fluids\lib\winx64
If it does not, I would uninstall and reinstall the software by right-clicking on setup.exe and choosing run as administrator

[P_e_a_R]

Checked downloaded file size: Its OK, 7.42GB
.dll exist in the 3 indicated places: OK
I'd previously installed Ansys student as admin twice before posting here. Didn't solved the problem.

Is there anything I should look for ? =/

I would try changing your PATH environment variable so that it starts with:
C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\
Meaning, I would cut the following and paste it at the end of the PATH variable value:
C:\Program Files\Microsoft MPI\Bin\;C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2018.3.210\windows\mpi\intel64\bin;C:\ProgramData\Oracle\Java\javapath;C:\Program Files (x86)\Rockwell Software\RSCommon;

Following your recommendations, I've changed the PATH variable, according to the images.
Didn't solved unfortunately.
When trying to launch fluent standalone, that error shown up. Little bit different, but similar to before.

Hello!

I am having a similar issue, when I open Fluent from workbench I also got the error: Fluent application failed to start.

I've also already re-installed Ansys, turned off Firewall, re-installed prerequisites as administrator without success.
However, when I open the Fluent standalone it opens perfectly
When reviewing the fluent console, notice that the following error is shown:
"Error: Cortex received a fatal signal (SEGMENTATION VIOLATION). Error Object: ()"

Would someone please point me a direction to solve this?
Thanks in advance.

[andremendes]

hey i have a very similar error with fluent. Did you find out how to solve it?

[P_e_a_R]

Hi Andr├®
Unfortunately I didn't reach the solution for the problem.

[George Karnos]

Hello All Can you please check the driver for your graphics card to verify that it is the latest driver available.
Run DXDIAG
This will show you the driver date on the Display tab.
An old example:

Thank You.

[George Karnos]

dll errors of this nature are very difficult to troubleshoot.
The issues could be due to dlls of an older version on the Windows\System32 directory or not having full administrator privileges when installing(Right-click ->run as administrator)
Microsoft has a tool that may help see where the issue is. It is called : procmon

[P_e_a_R]

Thanks for your effort in trying to help the situation.
The driver is recent (2019) and manufacturer seems not to provide a newer update. All the installation was done as admin.
For now I will just quit this subject and try to install another windows version in the future, expecting it will solve the problem.

Thank you very much anyways.

clean uninstall your antivirus and rerun the workbench. problem solved for me. my antivirus is not allowing fluent to access the network.

None of the suggested workarounds worked for me. But here is what did work for me:
I installed ANSYS on my D: drive, as I had very little space left on C:. Workbench worked fine, but Fluent did not. I tried everything suggested above and nothing worked. I also disabled my McAfee firewall, as previously suggested, but that did not make any difference either. I partially could start Fluent manually from command prompt, but it never fully started (the wheel kept spinning forever). So I cleared enough space on my C: drive and installed ANSYS there. And now Fluent starts without problem from Workbench.
