Sep 17, 2018 at 13:28 comment added user42582 using WhenEvent; If you're certain your system is correctly specified then I suggest you play around with WhenEvent until you discover a working specification. I could be wrong, but I don't think If can be helpful in this case.
Sep 17, 2018 at 13:13 comment added kosa For me, WhenEvent was giving such error. So, I started using If function. BTW, how did u approach it? How did u make the solver access its previous values?
Sep 17, 2018 at 13:09 comment added user42582 I tried solving it but got a NDSolve::underdet message "There are more dependent variables, {u[t],x[t]}, than equations, so the system is underdetermined"; in case my failed attempt was due to my erroneous equation setup, perhaps WhenEvent might seem useful
