The Generalised Adaptive Fast-Fourier Evolver (GAFFE) toolbox is a framework that greatly simplifies the solution of complex partial differential equations (PDEs) in an adaptive manner.

By default both the step-size and the mesh adapt to the problem at hand to optimise the speed of execution for a given nominal target accuracy.

The technique is N dimensional and can therefore be used to model diverse problems such as temporal solitons, spatial self-focusing or exotic space-time effects.

Currently the technique is limited to scalar fields.
