I use ls dyna for ICFD purpose and I use 3D models. For 2D models everything is perfect but when I try to run my 3D models after 5 or 6 hours of simulation it shows "possible mesh surface collapse". I mam not understanding How to correct this thing like whether to change the mesh size or my keywords are wrong at somewhere. IF someone can enlighten to this topic it will be very helpful

Hello Prithwish,
I also encountered this problem and tried many times but it didn't solve it. Have you found the cause of the problem now?
