Rigid body modes

“There are 628 rigid body modes…”

Hello!

I get this error when connecting “Assemble model” to “Analyze”. I cant figure out how to fix the problem.

Hi,
you have created a rectangular gridshell and set all the elements as truss elements. This means all of the elements are kinematic which you can see when you use the eigenmodes component and preview the deformation. You need to either brace the structure with diagonals or activate bending.
