Hello ! I encountered a problem, trying to numerically solve a differential equation. My equation looks like: A y''[x] - B y[x]' + C Exp[-Dx] == 0 with boundary conditions: y'[0]==0 , y'[E]==0 All constants A to E are known. Mathematica complains, that the equation is not linear. But in the online documentation I saw many examples of nonlinear differential equations, which all work fine. What is the difference between the examples and my equation ? And is there a possibility to NDSolve my equation ? Any hint on this would be of great help to me. Thanks a lot, Ronald -- Ronald Sastrawan Freiburg Materials Research Center Stefan-Meier-Str. 21 D-79104 Freiburg Germany Tel: ++49/761/203-4802 FAX: ++49/761/203-4801 EMAIL: sastra at fmf.uni-freiburg.de http://www.fmf.uni-freiburg.de/~biomed/FSZ/forschung-FSZ.html
