Exploding egg effect - an egg heated in a microwave oven

The dissipated power concentrates in the centre of the egg. In the physical experiment the evaporation of the water overheated in that area would cause the explosion of the egg - an experience quite memorable to many who tried it.

The goal of the simulation is to obtain the temperature distribution after the sample has been heated for 1 minute with the power of 625 W while the angular speed of the sample around its centre (and the centre of the tray) has been set to 1 rpm (revolutions per minute). The initial temperature of the sample is -5°, to facilitate visible heating effects.
