I've previously ran a harmonic anlysis of a motor and gearbox to determine the response from a unit applied force at the bearing locations to determine vibration severity. Now, I am intrested in quantifying the maximum force exerted to the base plate of the system. 

Here is an image of the system: 


GB LS and GB HS are point masses to represent the static shaft weight. GB input 1 and 2 have 1lbf applied in the X and 1 lbf applied in the Y directions. GB input 2 is 180 out of phase from GB input 1. 

All contacts are bonded. 

I would like to be able to output a force reaction vs frequency plot for the connection to the bottom plate. I've turned on nodal forces, and set "expand results from" to "modal solution". Is this approach incorrect? The simulation will not solve. 

I did notice workbench generated output parameters for the frequency response. Would anyone be able to provide a reason for why this happened? This is my first time seeing the parameter interface. 

Any insight or suggestions would be geatly appreciated. Thank you.
