I want to know whether the Pylith supports Gmsh to create a 3D fault model. If it works, please provide a simple example for reference. Thank you for your help.
PyLith v3 supports importing 2D and 3D meshes with and without faults from Gmsh. We do not yet have a simple example in the documentation. The procedure is similar to other mesh generation tools. You can find an example Python script at tests/fullscale/linearelasticity/faults-3d/generate_gmsh.py.
