Gas Match Field and Gas Equalize Volume DOPs

Recommended Posts

Hello fellow magicians,

I'm trying to better understand gasequalizevolume DOP inside FLIP Fluids and so far I haven't found anything usefull outside of the Houdini documentation and example files. So I tried to create a simple example file to test it out.
So far, I can't seem to create one of the necessary fields for gasequalizevolume to properly work, the goal field. I used a gasmatchfield DOP and imported a pre-created fog vdb with the name goal, and nothing happened. To debug I setup a multifieldvisualization DOP and set the density field to goal, but it doesn't display anything...

If some one could have a look at the file and point what I'm doing wrong...
Also, if you any information or tutorials on this subject I'd be very gratefull!

Thank you



EDIT: The Gasequalizevolume was wired in the wrong input. It needs to be wired into the volume velocity. Still can't get the gasmatchfield to work though...

OP probably has found the solution already, for anyone who has the same problem; 

Instead of using a gas match field, use a source volume from sop and use goal_volume as the target field. The gas equalize volume uses the goal_volume field to match. 
Be advised for some reason i had to turn on "two dimensional" in the gas equalize volume node.

I am using houdini 17.5 

hope this helps !
