Mathematical Function Use in ODEs??? - Jun 22, 2010 at 2:35PM

Does anyone know if it is possible to use named functions (e.g. sine) in the ODE "evolution"?  

[I want to simulate a "particle on a hoop" under the influence of a separate external force field.]

Yes. For example if you want to say that dx/dt is sin(w*t), your command should read

dx/dt=Math.sin(w*t)

Hope it helps.

The OSP parser within EJS can be used used to compute the ODE rate.  See how this is done in the Barrier Scattering model.
