Simulation Crash at Fault Creation

Hey, I am running a series of test on a SMIB and have noticed that some simulations with a fault at the POC that bring the voltage to around 0.05 pu cause the simulation to crash. I was curious if there was a way to ensure this does not happen, or if I simply am doing something wrong. Cheers

try to reduce the imposed stress of the fault and see if the problem persists:

1)reduce the duration of the fault 2)increase the impedance of the fault, so that the Isc magnitude is decreased (just temporarily to find the cause of the crash) 3)Reduce the time-step of the simulation 4)Increase the tolerance of the convergence (again, only temporarily)

Thanks for the reply, if I reduce the magnitude of the fault to the point where the simulation does finish how can I use this to determine the cause of the crash?
