Hey all , so trying to get this set up working myself at the moment , and hitting a wall with the driving force right now .

Ive got all of the fields set up , and am getting the volume attraction , i can see the force in the goalGrad vis , …but its overshooting goal by a lot .

I'm using a gas calc to add to vel field with goalGrad , so maybe thats where i'm going wrong .

if I am not mistaken Attract Fluid Tool from Volume Fluid Shelf in H11 does this effect, so maybe you can look inside the tool to see how it's done, or just use that tool
