Did you follow all of the steps when generating the mesh as described in Section 7.18.3 of the PyLith v2.2.2 manual? Note: Depending on your version of CUBIT/Trelis/Coreform Cubit, you may have to update the id numbers of entities.
See Section 7.18.5 for how to run the example, specifically the listing labeled “Run Step 1 simulation”.
hello,Thank for your attention,I run my code in a biger mesh,the code was ok,but when I use a small mesh(the same geometry),pylith generate the following error,how to correct it？
– Initializing fault ‘slab_top’.

The error message suggests that there is a problem with the topology of the mesh related to faults. Check all of your nodesets in Cubit to make sure they are consistent with the ones from the mesh that works. I also recommend using the mesh quality checks to make sure you do not have distorted cells.

Please provide more information about what you are trying to do. Are you running a simulation you created or an example? If it is a simulation you created, please provide a detailed description of the boundary value problem you are trying to solve (a diagram is usually helpful) along with your input files.
Hello Yanfukang, I want to ask you how did you fixed the error "Faces should separate only two cells, not 4” with your FEM mesh? Thanks for your time.
