Hi,

I have a problem where I am unable to run ANSYS Fluent on R2023.2. The application shows up very briefly on the taskbar then disappears. I have tried several ways such as running as administrator, uninstalling, clearning all ANSYS files, then reinstalling ANSYS Student, but am still unable to run Fluent. All other programmes (such as Design Modeler or Workbench) open as intended. I need help solving this as it is for my final year project.

To add on to this, I have also ran the following commands on Command Prompt:

set HOOPS_PICTURE=dx11
"D:\Program Files\ANSYS Inc\ANSYS Student\v232\fluent\ntbin\win64\fluent.exe" 3d -t2

To which Fluent did open but with the following error message:

I have tried to set HOOPS_PICTURE to opengl2, msw/win and opengl but to no avail. I have also updated the graphics driver to the newest NVIDA Studio and Game Driver and am still unable to open Fluent properly.
