how can i make smoke run faster and fill the objects

[jsyang]

Hi,everyone
Another question comes up again.i want to fille the 3 objects in this scene.the smoke runs very slowly in "M",but much faster in"A"&"X".the two letters are full in 100 frames.the letter "M" can't be filled.i don't know why,can anyone help me?[IMG][/IMG]

the way in the M letter is just longer than in the other letter, and even the strongest conservation looses its power.
if you are using nightly build i would suggest to drive the smoke by a spline, this will ensure uniform speed, beside this you can add some rotational movement

how to add some rotational movement,please?[IMG][/IMG]

For this scene I used a few emitters in each letter to overcome the problem that the M is longer than the other two. I can try to dig up the scene.

Here is the Max file for the scene - just adjust your sim resolution and you should be good to go.

thank you.i've thought the conserve parameter could not fall off.
