Thanks, i'll look into some your suggestions.

Thank you for replying. Its a nonlinear optics problem. I'm simulating the propagation of intense pulses through nonlinear materials with a system of nonlinear Schrödinger equations. The time step is of the order of femtoseconds and the total size of the spatial grid is currently several mm...

Hi all, first post :) I have a system of z-propagated nonlinear PDEs that I solve numerically via a pseudo-spectral method which incorporates adaptive step size control using a Runge-Kutta-Fehlberg technique. This approach is fine over short propagation lengths but computation times don't...
