this is the end goal of creating the cad model. stress evaluation and modal analysis. i attached some pics. fea model in mecway. load was 4600 rpm. the aero loads are very very small so they don't need to be modeled. i have checked that out previously. this is a delta computer case fan. the real part is much thinner and made with plastic. my part is aluminum and needed to be much thicker, because of that. this is just an example. i don't have the material properties for the real product.
