I try to run the frequency analysis for the engine mount (I attach the image )
in this case I create the remote mass of part A and placed in B
also fixed the bottom face of part B and I used pin connection in bolt areas and bonded contacts
here I used the custom material for rubber I give the properties of rubber like the young's modulus, Poisson ratio and mass density
but in simulation tree I can't access the rubber if I right click the rubber it not show any think
rubber not include in analysis it's in suppressed condition that's why?
and I want clear idea for doing this analysis
