I’m working on reproducing benchmark TPV205. However, the results are different from the SCEC website.
Although the rupture time contours are consistent:
the slip and slip rate history is different.
I would like to take the output at fault-station (4.5 km, -7.5km) as an example:
It is clear that my simulation is lack of the third/fourth pulse compared to the SCEC benchmark results.
The first pulse is the initial rupture front from the nucleation zone. The second one is the secondary rupture front from the free surface. The third pulse comes from the right fault boundary, which is set to be unbreakable.
What could be the problem? I have carefully investigated every parameter and the mesh, but couldn’t be able to trouble-shoot it.
Any suggestions will be greatly appreciated.
