FRF output for FEMFAT Spectral

I am trying to run Fatigue Analysis using FEMFAT Spectral. However while importing the pch file for Transfer Function I keep getting error saying number of modes in TF does not match number of modes in modal stresses. i have already tried to create set to output Acceleration but then the number of modes in TF comes out to be 0. So how do I output the results correctly for FEMFAT to read it.

hello @Prithvi_Raj ,

we are not supporting technical requests for Femfat. As a product in our partner program, we can only help with license and installation

Best Regards,

Hello Michael,
Thanks for the response .

Yes, you are correct that my question is linked to FEMFAT but I want to output the results from Hypermesh OPtistruct.
So, it can be seen as a Hypermesh Question .

I just want to know how to output the results correctly so that the number of modes and the number of Transfer Functions are the same.
