Edge to surface connection Hypermesh/Nastran

Hello,

 

I'm modelling a complex structure in Hypermesh with Nastran profile and I need to connect two components. One is a tube meshed with pshell elements while the other is a solid meshed with psolid. The tube is perpendicular to the solid surface but I cannot have the same mesh for various reasons. In Abaqus I would use a tie constraint between the edge of the tube and the surface of the solid but I can't understand how to do so with Nastran and Hypermesh.

 

I tried to use the cards BSURF, BCONNECT AND BCTABLE but I'm not able to figure out how they works.

 

Any suggestions would be highly appreciated.

 

Thank you!

 

Stefano

    Refer Nastran help to understand the significance of BSURF,BCONNECT and BCTABLE.

    You could also try this analysis with Altair Optistruct solver.
