Intro
The Fipy documentation covers the level set method as applied to a surfactant equation:
This is basically an ordinary differential equation consisting of the following:
$ \frac{d \theta}{dt} = k (1 - \theta) + S $
The way that it is implemented in the surfactant equation class, as linked to above, is slightly different, in that the formulation is solving a steady-state version of the above equations, making the timestep irrelevant (which is why the timestep is hard-coded as 1.0).
