Working on a fire simulation and I was confused about which value is more physically correct to adjust because I know adjusting reaction speed slows down or speeds up the fire simulation.
Any help appreciated!
A high Fuel value will bring more fuel and make higher (but also bigger and more agitated) flames. A low Reaction Speed will speed up the reaction and make higher flames as well. To make higher flames you can also try these factors:
Select the inflow object, enable Initial Velocity and choose a high value on Z:
Or select the domain and under Gas, increase the Buoyancy Heat:
