Dear Peteronz

Thank you for your information.

Ansys "Harmonic Response" takes the base sine-sweep spectrum as input, and calculate the  response. This should simulate the sine-sweep test, right?

Similarly, the "Random vibration" takes the base PSD as input, and calculated the PSD of the response. This should simulate the random vibration test, right?

Could you inform me which Ansys analysis type can calculate the FRF? The FRF does not need input sine-sweep spectrum. It only needs one/several points as input and one/several points as output.

Thanks and regards
