Intermodulation distorsion

hiall,
can any1 tell me how to do "intermodulation distorsion" analysis of capacitors in HFSS(if its possibe to do)?
thanx

I think it is not possible, since intermodulation effect is a nonlinear effect which cannot be modelled in HFSS using FEM. may be you need a time domain simulator that can model nonlinear effects.

thanx a lot
