The heat always evolves to an equilibrium, but you can design how the equilibrium should look like. * "Heat" button: Increase and decrease the prescribed heat * The heat can also be controlled by the LEFT and RIGHT button Tip: Change the heat and move the cursor over the domain in the "fly on" mode * Press the mouse cursor in any cell in the domain to "fix" or "unfix" the prescribed heat there. Tip: Assign different heats to different cells. Other buttons: * "fly on / off": Indicates whether or not change the heat "on the fly" of the cursor * Scale (1,2,3): Prescribes the number of cells (after changing the scale the scale button is blocked for purpose for a while) * Speed: Controls the velocity of heat propagation
