Shell thickness

[Leonor]

Hey there!

I'm having some trouble with abaqus.
I have a solid structure and I created a shell that covers it. I then deleted the structure and now I want the shell to have a thickness so I can apply mechanical properties to it (if there's any other way to do this without attributing a thickness it would also be useful).
I created this shell using the "edit mesh" icon (looks like a tool) that is available in the mesh module. I have already tried doing "tools - midsurface - assign thickness and offset" but abaqus says "The part does not contain any geometrical shell faces".

Can you help me please? I'm a bit desperate and I have my deadline for this project tomorrow!

 

[FEA way]

It seems that you have orphan shell mesh. Either assign shell section with proper thickness to it or convert it into geometrical part (Geometry Edit tools).

Than you so much!!
