I can't analyze

[mutluengineer]

Hello there. After creating the system, I cannot analyze. It says check geometry, but it doesn't give an error in geometry check. I did some research and it says the system cannot be resolved in modal installation. I couldn't solve the problem when I looked at the 3d frame... the project is attached.

Hi, beam part of K53 width (on B axis) is visible at the junction of K53 and K50 beams. Delete that part. A similar situation exists on the C axis as well.
