Hi guys!

I have a problem while making simulations on Ansys Aqwa.
I must get the RAOs of a small sphere (20 mm radius, moving vertically only) and the following error always appears when I try to solve the system:

STRUCTURAL MASS MATRIX DIAGONAL(S) ZERO FOR STRUCTURE#1

Can someone help me?

Hey,
You gotta add point mass for any floating Body. Make sure that the point mass is located on cob.
