Hello, Michael, do you solve the problem with ShellMITC4 in OpenSees?

Do you mean that you use shellMITC4 to run the dynamic analysis? Does it have something wrong with the mass modeling?

I am now working on a contact problem with friction effect to be included, however, the BeamContact3D could not converge all the time. So, what could be the problem for this element?
Thank you!

If I want to run two different analysis simultaneously like pushover and eigenvalue analysis, and they are expected to be independent, then what should be added between these two analysis? Thank you!
