Hello  Michal_par

It might be due to your graphics not meeting ANSYS Discovery Live Graphics Requirements.

  • Make sure your GPU meets the recommended hardware requirements (8GB GPU RAM)

  • Try running with a higher fidelity setting and/or with a larger GPU.

  • Try to reduce the simulation bounds by removing some parts of the model.

  • Last resort: Try increasing the feature size by thickening the walls, etc.

You can check ANSYS Discovery Hardware Requirements through below post:
