Nice one, John.
Yes, FEASolver, run the frequency analysis, but I have to question your modeling technique if you have 150 parts of the same material bonded together and you are meshing them separately. I would suggest that you merge all or most of the parts in your CAD model before exporting them to any FEA software. Everyone believes their "software of choice" can mesh anything, but to match the mesh of 150 parts is difficult. Merging the model and exporting a single solid will make this easier for the mesher.
Is there some reason why you need all 150 parts in your FEA model? If this is a linear static problem, seems like a single part should do.
What CAD modeler are you using? The difference between a CAD model and an FEA model is often huge. You may not be getting any interference, but are they in intimate contact? If not or if they are, but at a larger tolerance than the gap that the FEA software will catch, Algor may not think you are in contact and, therefore, may not be matching the mesh. If the mesh is lined up and the nodes coincident, the processor won't recognize the bond.
The model clean-up is under "Tools: CAD Preparation", I think.
