Hi there,

I know this is a solidworks forum, but since there's no Abaqus forum my only option was to post here.

I'm modelling a space frame chassis, inbetween some of the beam sections I want to apply surface shell sections - to create a sort of monoque but with the beams present.

Now I've done this but the beams seem to disappear when I apply the shell sections, almost as if they're replacing them. When I suppress the shell sections the beam sections reappear.

Is this just a case of rendering or are the beam elements actually gone? I spoke to someone who said you cannot have two different types of elements going through the same node - is this true?

I've tried meshing the whole thing and getting the error below

I've attached images for better understanding

Thanks
