  1. FLIP group based on collision vel

    Hi there, I just Need a quick tipp here. I'm trying to generate a Group based on collisions, so based on collisionvel. I'm using a gasfield to particle to add the collisionvel (renamed to col) to the Geometry. Then I wanna use a Little bit of vex to get a Group within a Pop wrangle or a wrangle within a sop soler. if(@col !=0){ i@group_collided =1);} Unfortunately I cant get any Group based on collisionvel. How do I actually get a Group based on collisionvel?
  2. collisionvel by group (flip)

    Hey ppl! So in a standard flip simulation, i'm sourcing collisionvel (vdb) from a source volume. How do you apply that collisionvel only to a particular point group? Not sure what i have to modify in the flip solver or is there a easier way to control this? Thanks!
