One of the key approaces in design simulation is to get the most information possible from the simplest model, so that your solve time is as quick as possible allowing for as many design iterations as possible. This presetation highlights to tools and approaches you can take to simplify your assemblies without reducing solution accuary and relevance. https://r1132100503382-eu1-3dswym.3dexperience.3ds.com/#community:52/wiki:M44dPg6nSqu8bfDKIYzSGQ
