  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!
