Dear Pylith developers and other users！
I’m interested in whether blasting load can cause fault failure，or the effect of stress waves generated by an earthquake on the stress state and dynamic rupture of the adjacent fault. Can I study the effect of high strain rate stress on fault failure by using a velocity boundary model on the boundary? If I want to simulate this process using pylith, are there any reference examples in the manual?
In addition, whether rate-dependent fault slip simulation can be realized in the same model as fault dynamics rupture process？
You can use a velocity boundary condition to generate seismic waves and try to trigger slip on a fault with friction. Fault friction is not yet implemented in PyLith v3, but it is available in PyLith v2.2.2. There are no examples of using a velocity boundary condition with fault friction in a dynamic simulation, but there are quasistatic examples. If you understand how to create BC from the examples, it is relatively straightforward to put the pieces together.
Thank you for your reply

When you refer to fault dynamic simulation here, do you mean the simulation of fault rate-dependent slip or dynamic fault rupture process
Fault with friction = spontaneous rupture or dynamic rupture (FaultCohesiveDyn component)
Dynamic simulation.= including inertia in the governing equations (required to generate seismic waves; Explict formulation)
