Hello, 

I am having trouble with ANSYS 2019 R2 FLUENT. 

While simulating, fluent is crashing. The event logger notes the following error:

Faulting application name: cx1940.exe, version: 0.0.0.0, time stamp: 0x5cb5e2bc
Faulting module name: dx11_2300_x64.hdi, version: 23.0.0.0, time stamp: 0x5a3b8363
Exception code: 0xc0000005
Fault offset: 0x000000000000d923
Faulting process id: 0x2f5c
Faulting application start time: 0x01d5407538359826
Faulting application path: C:PROGRA~1ANSYSI~1v194fluentfluent19.4.0cortexwin64cx1940.exe
Faulting module path: C:PROGRA~1ANSYSI~1v194fluentntbinwin64dx11_2300_x64.hdi
Report Id: 73317364-c0a4-4ff2-b666-65a9f9c6b7fd

 Is there any fix for this problem? 

Thank you.

If the code is running are there any errors in the solver?

[michaelmaalouly]

No errors appear in the solver while the code is running.

I run my simulations overnight, and it has happened twice now: I start the simulation, come the next day to check on it and I find that FLUENT crashed and that the program closed.

Are you using ANSYS Student version ?

What graphics card do you have on the machine ?

Open CMD Prompt, and issue the following command

"C:Program FilesANSYS IncShared FilesLicensingwinx64ansysli_util" -statli 2325@localhost > C:Tempstat.log

wait for a minute, then open C:Tempstat.log with notepad (or any text editor tool) and copy the entire content of it and post it here

I am using a full academic ANSYS license, and the GPU mounted on the machine is NVIDIA Quadro P1000.

Hi michaelmaalouly,

Thank you for the info.

Please try the following in this order

-Update the driver of your NVIDIA Quadro P1000 to the latest available according to Nvidia website (https://www.nvidia.com/Download/index.aspx?lang=en-us)

-Right click on the desktop then launch Nvidia Control Panel >> Manage 3D settings >> set Preferred graphics processor to be "High-performance NVIDIA processor”.

-Fluent Launcher -> Show More Options -> Environment , then add this 

LAUNCHER_FLUENT_OPTIONS=-driver opengl

Thanks,

Win

[michaelmaalouly]

Thank you for your help Win.

It seems like updating the GPU driver solved the problem.

[tsiriaks]

That's great to hear !

Thank you for the update.
