Computer simulation of dendritic growth in a cooling Al+Cu alloy. We have simulated a cube with a side length of 0.2125 mm consisting of liquid aluminum mixed with 2% Copper at an initial temperature of 919.25° K. The plot shows the concentration gradient of the copper around the solid dendrite. As the aluminum crystallizes first, the liquid phase next to the dendrite exhibits a higher Cu concentration.

The parallel implementation was carried out with LibGeoDecomp. The model was provided by Klemens Reuther of the Department of Metallic Materials, FSU Jena.
