[CIG-SHORT] Rate and state friction friction.linear_slip_rate nondimentional?

[Ekaterina Bolotskaya]

Dear Pylith developers,

I'm using rate and state friction model in my simulations.
I found in the manual that friction.linear_slip_rate is a nondimentional quantity that should be about one order of magnitude larger than absolute tolerance in solve.

Could you tell me how Pylith uses this nondimentional value (friction.linear_slip_rate) with my dimentional slip rate and reference slip rate? Or how does it nondimentionalize dimentional rates? And what should the relation between the three approximately be? I just want to make sure the three of them are reasonable with regard to each other.

Thanks!
