      I'm running an cfd analysis in ansys fluent and after a couple of iterations, the window just closes it self. Here's the error :

      ==============================================================================


      Node 0: Process 15016: Received signal SIGSEGV.


      ==============================================================================


      job aborted:

      My system config: i7 11th gen 64gb ram 12gb graphics card.

      Let me tell you this is my new system, and I installed everything just today itself. The things that I have tried and havent worked:

      1. Running the simulation without UDF
      2. re-installing windows
      3. Simple cfd analysis is completed, the problem lies with complex flows.

      Can anyone help me please?

      If the solver is failing after a couple of iterations and it's not the UDF, check the mesh quality. What models are you using?
