Wrong results at Lyniar Dynamics Study

Hello!

Today I checked with "SolidWorks Simulation Verification Problems" some Static Studyes which were corect, but at the Liniar Dynamic, I made one test on 2 computer and both are getting the same result, but not the same with those from SolidWorks Simulation Verification Problem, Simply Supported Thin Plate under Suddenly Applied Pressure.

What shell I do?

Thanks!

And how can I verify the Fatigue Study, on "SolidWorks Simulation Verification Problems" I don't find something for that?
