Hi, could this be related to creeping associated with low traction? Did you solve the problem?
Hi, the slipping elements are within a strongly velocity-weakening regime, there should be no major creeping. I did not solve the problem, but I assume the observed slip rates are too low to have an impact on the results.
Hi, could you try the dr/cpp branch or the master branch after #604
We observe some weird slipping behavior of some elements at the bottom of a fault zone (thin layer of drastically reduced seismic velocities and elastic moduli around the shallow part of the fault).
I wrote a script that calculates the rise time (time the slip rate is above a certain threshold) and found that these elements are slipping almost the entire simulation time (100s):
The produced absolute slip is very low, but is visible when the colorbar is saturated:
The fault zone leads to trapped waves, and therefore to strong stress concentrations. Dynamic triggering of these fault parts would not be something unexpected, but the distribution of elements slipping the entire simulation time, next to elements that do not slip at all, does not look physical.
We used the seissol branch thomas/RS_positive_normal_stress and ran it on SuperMuc. The mesh resolution on fault is 75m and we used order 5.
