Mathematica NDSolve

  1. Sep 10, 2009 #1
    Is it possible to numerically solve a differential equation (in Mathematica) that is composed of the solutions to another numerical differential equation such as

    Sol1=NDSolve[f'[x]= f[x].....]
    Sol2=NDSolve[g'[x]= G( g[x], f[x] ).....]

    where G(x) is the a function of the interpolating function produced from the previous ODE?

    I have tried writing the G(x) as by replacing all the f[x]'s with Evaluate[f[x] /. Sol1] but I get the error
    "NDSolve::ndfdmc: Computed derivatives do not have dimensionality \consistent with the initial conditions."

    Any suggestions?
    Thanks!

    What version of Mathematica are you using?

    Thanks
