The program stops unexpectedly
My file works, but it stops suddenly after a period of time. I have tried many methods, changing the grid, changing the parameter settings, changing the initial conditions, and changing the wellbore stabilization. But the result is unexpected termination, and the time of stopping is just differe nt. Sometimes it stops after running for dozens of days, sometimes it stops after more than a hundred days. This problem has troubled me for several months, and I can't find a solution. Attachments are input and output files.
