Hello, I am using PIC method to do a simulation and it begins well but after running for about hundreds of steps, it will show the error as ‘DT < DT_MIN. Recovery not possible!’ and the simulation will stop.
This situation may terminate at different steps during each same calculation. What is the reason for this? Thanks a lot!
