Hey everyone, I am a newbie in HYperMesh, so please bear with mine mistakes. I modelled mine roll cage in SolidWorks using Weldments and imported the CAD geometry as step file in Hypermesh. I extracted the midsurface of solids and meshed it using 2d elements. But the problems comes in the region where joints/welds will be there. Also, some surfaces remains unmeshed. The quality check for meshed elements are also not satisfactory. 

So, please help me out in rectifying this problem. I have attached the step file.

    can you provide some pictures of your model and problematic areas?

     

    In these cases try trimming the surfaces into smaller portions and try meshing them.

    I have attached the screenshot of the region where welds will be there and gaps remain after midsurface extraction. Also, I tried to use extend and trim tool for smoothing of the surface weld, but could not succeed.

    How to do it? Please help.
