I wish to add a few details to my previous post: 1) I am solving using NDSolve 2) If I try to solve the same equation using a different set of coefficients and source (e.g., I tried with D = 1, U = 0, S = 0) then the situation looks reversed: when I set the boundary condition at the extreme of integration then the solution looks correct, whereas when I set it a bit beyond, the solution is wrong.
