Hello sir,
I found that once 6DOF solver can't converge (always), the cylinder would rotate almost 180º(as the pic shows:Theta(deg)) within the first time step, which is unreasonable. Plus, the circular cylinder deformed to a elliptic cylinder although it's assigned to Rigid body. Is that possible we misunderstand the statement in user guide? I've checked the theory guide, I'm sure that in six DOF properties panel, that 6 inertia tensor values are defined relative to its CM/CG. But when one DOF rotation box is checked, maybe moment of inertia isn't relative to its CM/CG? Implicit update interval is always set to 1. I've tried hard but failed to find out the bug...
