Hi mdti

Thanks alot for your answer. my model and ref COG is the same (0 0 -89). and it is so strange for me that why my model is acting different. It has been a while that I am stuck with this issue. I was wondering that maybe my problem is the connection stiffness, bc it seems that it is not connected with time domain analysis, I turn on beta option and Include Linear Connection Stiffness Matrices in time domain analysis, but still does not see any changes,

Do you have any suggestions for me?

Thanks for your time
