[CIG-SHORT] ask for help about simulation of wave field with dynamic fault

[Charles Williams]

Dear Yao,

Sorry for the slow response, as I've been away.  I'm also posting your question on the cig-short mailing list, which is a useful resource for PyLith-related matters.  If I'm understanding your questions correctly, the answer to the first one is both.  I believe that PyLith can include both spatial and temporal variations in tractions on the fault (Brad can correct me if I'm wrong on this), and the simulation also includes traction changes for spontaneous rupture.

In response to your second question, I think the tip means that static simulations are easier to set up and run, so they make a good starting point for understanding how to set up a simulation.  Also, several of the examples in 3d/hex8 use fault friction, so these can be a good place to start.

Cheers,
Charles
