Hi all,

I have a 3D structural model of a concrete dam made of touching massive blocks, where there are hundreds of contact pairs with friction.

When I change any contact property, like friction coefficient or penalty factor COMSOL freezes for 5-10 minutes before the interface returns responsive, I suppose it has to write the property to all contact pairs.
It also takes the same time to startup every time I try to solve the model, and it gets quite annoying to wait for minutes every time I edit a setting.

Do you know any tricks or settings to speed-up the program?

Thanks, Matteo
