Hi all.
I need some suggestions about how to model a dislocation source (Okada type). The source is modeled as a couple of contact boundaries. I want to put some friction on the surfaces and I add the friction node (under the contact node in Solid mechanics). After, I planned to made a comparison with the results from a similar model to see if they are comparable. From Comsol, gotthe same results only if I choose a value friction = 4. But from what I understood the friction coefficient should between 0 and 1 in Comsol, as 1 should be the maximum friction. Can somebody explain this to me? I tried to see something more in the knowledge base but coudn't find anything. Maybe I am not considering some general conditions??
Thanks to all who can help me. Chiara
