Forest fire simulation 1: Slow combustion

This movie shows the time development of the temperature field in a simulation of slow combustion in 2-d when the background reactant concentration (e.g. trees) is uniform. As the time passes, growth sites emerge due to thermal fluctuations -- there are growing clusters of various sizes present in the system. Growth is radial since the background is uniform. After some time, growing clusters collide. Red denotes 'hot' and blue 'cold'. Due to dissipation the centers of the clusters start to cool as time passes.

oh, yeah, that's really slow :)
