Hi, I have a question about popAdvectByVolume in popSim. There is a option parameters > update velocity and velocity blend. Instead of blend, I want to add two popAdvectByVolumes, but I have no idea how to use popVop as first picture shows
As second picture, I tried to set first popAdvectByVolume as velocity update, and set second one as force update. I was thining two combined vels = vel + force But it's not working exactly.
Does anyone have idea how to set up vopPop? thanks!
