Using Simulation Motion, has anyone simulated or investigated design parameters in boat dynamics? Specifically, a buddy of mine is interested in determining "...at what roll angle the boat will sustain and still be self-righting unless taking-on water...". Apparently some design variables called "meta-center", "center of bouyancy" and CG come into play, here. I have not done any of this type of analysis, so any suggestions for software to use for an application like this is appreciated. This buddy of mine does not want to model fluid flow or gas/liquid interfaces - he's just interested in somehow using rigid bodies, springs, masses and dampers such as what Simulation Motion offers. Thanks for any suggestions.
