Hello, I am trying to numerically solve a 2-dimentional (x,t) ODE system. The general solution is like, for all x in (0,1), D[ f[x,t] , t ] == g1[ x, u[x,t] , Integrate[ f[y,t] , {y,A,B} ] , t ], D[ u[x,t] , t ] == g2[ x, u, t ], where g's are functions, for which I have already got their explicit expressions. But let me omit, as they are so complicated. The problem would be that A and B are the values of InverseFunction of f, namely, A = min{ y such that f(y) = x } and B = max{ y such that f(y) = x }. Can anyone tell me if NDSolve can handle, in principle, inverse functions like this? If so, would you tell me how I could do that, please? Thank you very much for looking at.
