Get clustered frequencies from Modal Analysis without running harmonic analysis by python script

Hello,

1) is it possible to get the clustered frequencies from a modal analysis without the calculation of a harmonic response (with the solution method: Mode Superposition)?

2) is it possible to determine the step width regarding cluster numbers?

Backpground:

I am currently running a model by script over and over again with different settings using a Python script.

The workflow in short is:
1. Run modal analysis
2. Run harmonic response (solution method: Mode Superposition)
3. Write / Export the Clustered Frequency in a csv-file
4. Make Settings for harmonic response (solution method: Full) with the clustered frequencies and more damping in specific springs
5. Run harmonic response (solution method: Full)

I would like to omit the analysis in Step 2.

Thanks in advance for your help

Check out this post. It may not be exactly what you want, but probably a starting point.
