Hello Everyone, 

I am trying to run Abaqus sumulation on some step files I generated using Rhino. I have multiple sweeps and they are bollean unioned to each other. I imported the file using in Abaqus part import function and I am trying to generate the mesh. The problem I am facing is, the part file is solid but when I generate the mesh it only creates mesh on the surface and the part looks hollow. Please help me figure out what could be causing this problem.
