smoke density

[Hello world]

Hi I am new to volumes

I have a volume source and it just sends out lot of smoke without depleting.

1)how can we stop the emission of the smoke so that it looks like a smoke explosion shooting at some little time and stopping.

2) do we need to animate the SMOKE AMOUNT in the emitters tab of the pyrosolver node or do we need to use any microsolvers such as gas dissipate?

Gas dissipate would get you the dissipation in density (or any other field of your choice).

As far as stopping the emission is concerned, you can animate / use expressions

on the activation field on the fluid source dop or the density parm in the

source volume SOP your using at SOP level. (Assuming your running H12)

aha whats the approach used in H11?

cheers!

well for H11 I used to source using a custom fields.

attach the source density source using sop saclar field dop and use that to source your density

at the post solver step (last input of the solver)..basically you add the density data you attached with

the sop scalar field sop to the density solved in the post solve stage.(quite similar to how its done in H12)

simplest way would be using a gas field vop and adding the source density to the "density" data.

depending on any additional fields you might be using (such as temp, divergence etc) which might be

dependent on density (depending on your setup) you might need to modify your setup as well.

gas dissipate is the same I believe.
