How to set dynamic source in CMTSOLUTION file? #1469

Dear all I tried to use CUBIT to build a model and simulate the propagation of seismic wave, but after I changed the values of latorUTM and longorUTM in the CMTSOLUTION file, the sema file presented would not change. I think I set the dynamic source wrong., Here is my CMTSOLUTION FILE:

To set a dynamic source (which means solving the spontaneous rupture process on a fault overned by a friction law) follow the guidelines in section 6 of the manual. The CMTSOLUTION file is not used in dynamic rupture simulations.

@jpampuero So change FAULT_STATIONS and Par_file_faults?
