Exploding egg effect - an egg heated in a microwave oven
Fig. 3. General view of the structure
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.

Microwave oven containing the rotated load
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.

Microwave oven containing two rotating objects
Consider now a scenario with two physically disconnected objects, each rotating around its own axis (which in this case is one of its vertices). Note that a distance of several cells in maintained between the two objects on the FDTD mesh. Heating details dialogue confirming the action settings in the Movement details dialogue.

Microwave oven containing two load translation
In this example two objects move iteratively in the xy-plane, each between its own four positions. Each of these objects must have a different name. The movement is along a straight line at any particular BHM heating time step, but the overall movement trajectory may be arbitrary. The user must ensure that the movement is physical - two different objects must not occupy the same volume of space at a time, and naturally, no objects may move outside the cavity.
