As I encounter with something similar before, I recommend starting with this video:


- what is the actual condition you're looking for? for friction, you can find it in relation defined under contact


- I don't think there is an estimated time for your simulation unless someone did the same thing as you.

start with a coarse mesh and run it to check the time. You might assume that if you doubled the number of elements, you will get doubled time, but this is not a rule also.
