Hi Virgil, You can tell NDSolve to use a fixed step size, but I do not know how to set it to a specific value, besides setting a maximal value NDSolve has an options "Method" that can take a "controller" with the value of "FixedStep". E.g.: eq = {f'[t] == f[t], f[0] == 1}; sol = f /. NDSolve[eq, f, {t, 0, 0.01}, Method -> {"FixedStep", Method -> "ExplicitEuler"}, EvaluationMonitor :> Print[t]][[1]] hope this helps, Daniel Virgil Stokes wrote: > Is there a way to force the step-size to be fixed when using NDSolve? > Note, I am using Mathematica 7.0.0. > > --V.
