Hello, 

I am having a same problem with you.

I tried to analyze the beams, but the AnalyzeThI component turned out to red with this error:

"1. Singular Stiffness-matrix: Can not solve static system.
Make sure that boundary conditions are set so that the structure can not move in rigid body modes.
When you analyze a flat shell structure lock the rotation perpendicular to the plate in at least one node.
Use the 'Eigen Modes'-component and activate the display of local coordinate axes: The first eigenmode will be the rigid body motion."

I also have 530 elements. What should I do?

Thanks a lot!

Niki
