HinnYour geometry seems a bit complex and perhaps it is not easy to use shared topology - not sure, but perhaps you know if you can make it more simple and thus make it easier to use a shared top. Unfortunately I can not help much with that, but as we said the nozzero or high freq. for rigid body modes, could possible be due to the contacts, so that is my feedback overall.nnGood luckErikn
