I am learning to use PyLith. I attempt to run the 2D magma reservoir using poroelasticity example. However, generate\_gmsh.py does not work. I have not altered the file at all- it is exactly as it was in the original down…

Dear PyLith developing team, Thanks for your continuous effort. I am building a toy model of a fault embedded in a box cutting two layers of materials. The setup looks like this: I took care to mark the fault edges…

Dear everyone, I working on crustal deformation analysis for the first time and I am very new into geodynamics simulation workflows. I have seen studies of the integration of slab geometries (as in slab 2.0, by Hayes et…
