Resolution Divisions

– The High Resolution option lets you simulate at a low resolution and then it uses noise techniques to enhance the resolution without affecting the overall smoke/flame motion.

Useful if you want to set up a low resolution simulation quickly and later add details without changing the overall smoke/flame motion.

– In this example (both at Tab Settings – Resolution Divisions =32) you can see how the Tab High Resolution – Resolution Division parameter adds details to the smoke/flame without affecting the overall smoke/flame motion.

– Another example (both at Tab Settings – Resolution Divisions =20, very low so the difference is more evident!):

– In this last example two simulations are compared:

– The 1st at Resolution Division=5 (and Tab Settings – Resolution Divisions =20)

– The 2nd at Resolution Division=1 (and Tab Settings – Resolution Divisions =100)

– It is supposed that the two simulations reproduce the same level of details (5×20=100 and 1×100=100)

– Note how the behavior of the two simulations changes despite the level of details:

– As you can see “Tab Settings – Resolution Divisions” and “Tab High Resolution – Resolution Division” are not equivalent.

– By using different combinations of these resolution settings, you can obtain a variety of different styles of smoke.
