RESVEC Modal Contribution

Hello everyone!

I'm performing an analysis where I find the modal contribution (SDISP) in a linear modal transient analysis. My problem is that I have 18 RESVECS that introduce weird RESVEC modes that optistruct states have the most contribution. Can I get rid of these RESVECS from the calculations or can I use another approach?

Regards

RESVEC is on by default for mode based procedures like modal FRF and modal Transient analysis. Under Subcase definition of loadstep step set RESVEC option to No.

Thank you Rahul, I have actually tried that but it gets overwritten since I use TLOAD1.

I think this is intended.Read the the third comment of the attached screenshot from help for RESVEC.
