Dear Frank:
You mentioned in the last workshop that the displacement from Multiple Support Excitation is total one but that from uniform Excitation is the relative one.
How about the acceleration from Uniform Excitation?
Is it relative or total acceleration ?
Thank you.

eta value in uniaxialMaterial Elastic
I tried several times to find out what eta means.
My conclusion is k=(1+i* eta)K. That is the coefficient of histeric damping.
But I'm not sure.
