Impact of a fault on surrounding faults

[Evelyn0416]

I tested the “crustal-strikeslip-3d” with pylith 4.1.3, and only added the slip displacement on the main fault, but it doesn't react on the branch faults. I don't think that's reasonable. Any suggestions or help will be greatly appreciated.

What do you mean by "it doesn't react on the branch fault"? If you only specify slip on the main fault, then there will be zero slip on the other faults.

@Evelyn0416 Are you expecting frictional behavior on the branch fault? If so, you need to specify that rheology, and currently that works in PyLith 2 but it coming in PyLith 3.
