![]() ![]() You can use it in the following web version of the model (press go button, and then click whenever you want to add ignitors). The Visible-Particles? switch will change between seeing the incandescent particles moving or seeing the flame effect on the air patches. Y-speed value controls the velocity of the particles, and the density slider will control the amount of incandescent particles that a particular ignitor will produce (in fact, it is a probability of production). You can set up a value for the wind (negative values blowing to the left, and positive ones to the right), and switching on the Varying-Wind? variable, the wind will automatically change its strength and, possibly, direction. The Boxed? option will make vertical borders to act as walls, so, once the particles are there, they only can move upwards. All we need now is to color the patches in order to show the flames (by default, the particles will be hidden), and add some extra functionalities to create ignitors with the mouse (places where the incandescent particles born) or wind effect (some horizontal movement to the particles). That's all the important to get very realistic flame effects. Patches-to-move is a report that returns only the patches above the particle. Report (patch-set patch-at 0 1 patch-at -1 1 patch-at 1 1) Patch Report: Returns the patches above it It modifies the Temperature of the air patch if location is out of the world, the particle is removed ![]() It moves up, to one of the cells with higher difference in temperature Set Temp-Part Temp-Part - ifelse-value (Temp-Part > Temp-air) ![]() The cooling depends on the temp of the cell it occupies Every Particle gets cooler, ascend and heat the air cell Reduce Air Temperature by natural cooling. Only particles with positive temperature will survive, it is not worth to keep alive particles that will not produce new fire.Īll these ideas are implemented in the next procedure: to go.Simultaneously, every air cell diffuse its temperature to neighbours cells (according to a Heat Conductivity parameter) and all of them get a little bit cooler. ![]()
