Stochastic Allen-Cahn equation
Discretized stochastic Allen-Cahn-type equation on a torus. The initial condition is random. The first simulation shows a view in 3D.
In the next simulations, time has been accelerated quadratically, to compensate for the process' slowing down.

These are for weaker coupling.

Now the dynamics is modified in such a way that the total magnetisation is zero. No time accelaration.
Another version, with weaker coupling. Time has been accelerated quadratically, to compensate for the process' slowing down.
