Interseismic modeling for Intersecting Strike-Slip Faults (3D) example

PyLith
1

Dear Sir/ Madam,

I am interested in modeling interseismic period for intersecting strike-slip faults.

In the example:

I read the modeling is for coseismic slip, which has zero displacement on the sides of the block (or zero boundary condition) (please correct me if I’m wrong).

I wonder can I modified the cfg and applied Simple.db and Dirichlet boundary condition at the sides of the block to model the interseismic phase of the faults? Is the intersecting faults compatible for that?

Kindy advice.

Thank you in advance.

You can modify the Dirichlet BC so that there are nonzero displacements on the boundary. Refer to examples/strikeslip-2d for a demonstration of this.

Note: You will likely want to view the documentation for the “stable” release, which is at PyLith — PyLith 4.2.0 documentation or select the version of PyLith you are using in the lower right corner. The documentation at https://pylith.readthedocs.io defaults to the development (main) branch, which has some differences relative to the latest release.

Thank you @baagaard
I will look at the links and try it

Thank you!

Dear @baagaard,

I would like to model 3d multi segment faults (like in this example), but with fault friction, similar to FaultCohesiveDyn in the prior Pylith (version 2). But in the current manual I could not find FaultCohesiveDyn (in Pylith version 4 or 5).

Can I use the prior Pylith (version 2) to model the deformation using fault friction of multi segment fault similar to this example?

Kindly advice. Thank you in advance.

Faut friction is not available in PyLith v3 or later. This feature is currently under active development.
