Hi, I have the same problem, but my geometry is complex shaped without any symmetry axis, so I'm expecting a non diagonal symmetric inertia tensor (6 dof) for my 3D body. SpaceClaim measure the area moment [m^5] of the body but along the principal axis of inertia, I multiply this tensor (diagonal) with the density [kg / m^3] and I find the inertia tensor in [kg m^2]. I'll put this tensor inside the properties box, the center of gravity and i have no idea on how to compute the "rigid body orientation" .
Simulation goes, fluent solver converges in few iteration, the body falls inside the cylinder with both rotation and traslation . But why i'm still having the message "six dof angular solver do not converge".
Any suggestion on how to compute correctly this inertia tensor ?
