Dear Community：
I am currently working on a dynamic rupture simulation using SPECFEM3D. My model involves two dipping faults with opposing dip directions (one dipping East and the other dipping West). Both faults rupture to the free surface and partially intersect in the middle section of the model.
I have encountered a challenge regarding the mesh quality. Specifically, in the intersection zone, the Equiangle Skewness of several elements exceeds 0.75. I am concerned that this high skewness may affect the stability and accuracy of my wave propagation and rupture results.
I have attached my journal file (.jou) below for reference:
mk_model.jou (29.0 KB)
Could anyone advise on how I might adjust my modeling process to reduce the mesh skewness and improve the overall mesh quality in these areas?
Any suggestions, tips, or guidance would be greatly appreciated. Thank you very much for your time and help!
Best regards,
YuanYi
