Hi,
I’m trying to make a structural simulation of fractal geometries. I identified all the beams, supports and loads. But I cannot connect them all. My main column does not affect the simulation and some the secondary beams getting dissappear during the simulations. I got these error each time:
“There are 48 rigid body modes in the system. This means some parts can move freely without causing deformation.
Try to use the ‘Eigen Modes’-component and activate the display of local coordinate axes: The first eigen-mode will be the rigid body motion.
If this does not help, check whether you have a pinned support directly attached to a hinge. A hinge introduces an extra node which may cause the problem.
When analyzing a flat shell structure one has to lock the rotation perpendicular to the plate in at least one node.”
How can I fix this problem?
