Problem "Element #237518 is not active but within the active part of the edge list" #12

Hi, I tried to simulate a strike-slip earthquake with a short but rapid strike-slip event. I created a 1000-m * 1000-m grid with 5-m resolution. First I generated a stream. Then I set a strike-slip event. The runtime is 10 year and slip rate is 500 mm/yr when uprate and other parameters like KB are zero because I want to use this way to simulate an instant strike-slip event which creat about 5-m offset. The faultopt is 100-m. But when I ran the .in file, the problem "Element #237518 is not active but within the active part of the edge list. Error in mesh consistency" arised. I don't know whether CHILD doesn't support that method? Or other reasons there. I tried to solve this problem by adjusting the seed. But a new problem "Segmentation fault (core dumped)" appears and no other error messages, whic confused me again. I would appreciate it if anyone could give me some advice.

Thanks for posting this issue. I was going to suggest adjusting the seed but it seems you tried that. Another thing to try would be doing the offset in two or more separate steps.

Also, here is some relevant literature that might or might not be helpful. Some of these used CHILD and some used newer models created using Landlab:
