Hello,
I have a question regarding thick shells (Tshell). I have modelled a thick shell and I wanted to execute selective mass scaling on it. I activated the IMSCL card in Control-Timestep making it equal 1. The problem is that the non-physical mass is added to the low eigenmodes too, which doesn't make any sense.
How can I activate selective mass scaling for thick shells correctly?

Hi @geremy,
Do you have any constraint definitions like *contact_tied or *constrained_spotweld?
