Hi! I have one question: can anybody tell me why the Runge Kutta implemented into mathematica in NDSolve always crashes as soon as I add a function looking like y'[t]==1+Tanh[4-3*x'[t]] ? I always ghet the error message "inconsistent or redundant transcendental equation". The same set of equations I want to use was working in Matlab without problems. Please tell me if you have any idea. Thanks Margit
