help! how to simulate the torsional stress of a shaft in solidworks

thanks for your help,but maybe I didn't describe my question exactly,so you just offered  the basic and brief process.in fact I focus on boundery conditions setting ,how to exert load （torsinal moment ) and how to directly view my expectable result  ,which is similar to transmition shaft bearing torque on both side and its derformation is torsinal deformation (that is to say , The shear stree on the cross section is proportionate to the distance from the center );so can you understand what I intend ?

yes! that is what  I focus on.and I have explained what i intend to Rosario Marceli,who replod me generaly about that question.so I feel oblied to iterate that I just modle a transmition shaft which bears torsional moment on both sides and I want to get shear stress on cross section,of course , the shear stree on the cross section is proportionate to the distance from the center,and you can refer to the attachment below, expect your help ,thanks !
