Hi Shin,

I just translated your query and trying to answer it.

You can do FRF and PSD without having modal analysis in the same .fem file.

You can only refer the EIGRL/EIGRA card in METHOD field. You can reduce the frequency requirement while defining FREQ card. Please go through the below link for various FREQ card definition and their use cases.
