Re: Fixed Time Step for NDSolve
Hi, probably not. I would not advice to remove the step size control. Typical a inital value solver with constant steps take more steps and accumulate more rounding errors than a solver with stepsize control. You can still use the InterpolationFunction that comes out form NDSolve to create a table of data with constant increment. Or you may have a look into the ProgrammingInMathematica`RungeKutta.m package that make a constant stepsize integration.
