PSD outputs from MotionSolve

Hello

I have a question which I cannot answer myself. Let's suppose I have a PSD input for road roughness.

I want to find a static solution from motionsolve, then export FRF relating inputs as wheel-contact displacements VS outputs (accelerations or even stresses).

I cannot find any detail in the documentation and I do not want to go for a time-approach because this problem can be perfectly solved working in the freq. domain. I remember this can be done in ADAMS, but I cannot understand if motionsolve allows having FRF.

The only detail I see is exporting LTI as A,B,C,D matrices to be then re-worked outside in COMPOSE.

Any help?
