Also, PyLith is able to solve all of these problems.  At present, however, it is not able to solve a dynamic problem and a quasi-static problem at the same time.  The only way to do this at present is to first run the quasi-static problem and then use the state variables from that problem as input to the dynamic problem.  Note that this will in general involve two different meshes, since the mesh resolution requirements are different for quasi-static vs. dynamic problems.

Cheers,
Charles
