ANSYS 2019 R2 FLUENT crashing

      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

      Thank you for your help Win.


      It seems like updating the GPU driver solved the problem.

      That's great to hear !


      Thank you for the update.
