Dear everyone,
I have 2 questions.
-
This is a basic question but I need to make sure about the slip sign. Following the manual book page 93-fig 6.2, positive value refers to left lateral, reverse, and fault opening slip. But I just realize in the examples/2d/subduction, fault_slip_coseismic.spatialdb file has negative value for the slip. Which indicates slip for normal fault. I check the finite fault data from Hayes, the slip is in positive value. I also check the fault_slabtop_coseismic.spatialdb in the examples/3d/subduction/spatialdb, the slip is also in positive value which indicates reverse slip. Which one is right?

I am currently learning to simulate spontaneous rupture using step5 in 2d/subduction. I use my own geometry and obtain an error as :
Nonlinear solve did not converge due to DIVERGED_FUNCTION_COUNT iterations 3022
[0]PETSC ERROR: --------------------- Error Message --------------------------------------------------------------
[0]PETSC ERROR:
[0]PETSC ERROR: SNESSolve has not converged
How can I solve this issue?
Thank you for your assistances.
Best Regards,
Alvina
