New to Workbench, question about interferences and materials

New to Workbench, question about interferences and materials

New to Workbench, question about interferences and materials

(OP)
Hello,

I am new(ish) to Workbench and have a couple questions.

First question:
Is there a way to specify a different material for each part in an imported assembly?  I am working in SolidWorks and have an assembly that I open in Workbench to run an analysis on and from what I can see it only lets me specify one material for all the parts.

Second questions:
The assembly that I am working with includes a shaft and a housing, and I want to calculate the stresses in the parts when a pressure is input to the shaft.  The shaft has a shape to it in which when the pressure is added, it should deform and hit the housing.  I cant seem to find a way to calculate the interference pressure(force) between the shaft and housing, either it gives me very odd deformations, or it deforms as if there was no housing.  I tried to run different analyses, changing the Connections Type, but it doesnt seem to be giving me the correct answer.  If I run an analysis on just the shaft without the housing, I get a deformation that appears to be correct and expected.  Does anyone know how to analyze an assembly and have the solution show what the true deformation/interference would be?

Thanks,
Nick
