I'm sorry I don't know what you really mean. i am not so expert but i used unstructured mesh with octree type i ran script control befor defining global mesh setup(global mesh size) and seved that after computing mesh. i added curves ,points and surface to proper BC.(actually to a proper part) i start with surface meshing and then computing.Is this problem?

You are using ICEM?
Did you check the geom it built up from the old mesh to see if it it correct? Make sure lines and points are generated correctly and not just surfaces. You might need to script in a geom Build Topology after generating geom from old mesh to correct this. If geom is all ok then try decreasing the Edge Criterion for the Octree Volume mesher. |
