Hello,



I am trying to simulate a flow over cylinder in 2d. I have created a mesh using gmsh. I am using k-epsilon model.



When I try to run the solution using SimpleFoam, after 4 itr, it starts to generate stack trace and gives:



Backtrace:

If anyone knows what is the error, please let me know.

Currently its all tetrahedral meshes since I havnt put Recombine command in gmsh file. But even with that command, the mesh changes to all prism but it still generated stack trace.
