MOHAMMAD67 Member Mohammad Fereshtehpour Join Date: Jul 2011 Location: Iran Posts: 61 Rep Power: 14	Dear Foamers Hi Recently, all of my simulations were blown out after 1 or 2 seconds. I use combination of hexahedral and tetrahedron meshes (hybrid meshes). Is the blowing out related to this? I checkmeshed and every thing is ok. Before that I used netgen3d for meshing and I didn't have any problem. After a lot of run, I believe that the problem definitely arise from the meshing. But I don't know how to deal with it.
