Crosspost from Odforce, as I hadn't any luck over there.

Hello Houdini pros!

I'm using the FLIP Solver's Reseeding feature, but it doesn't seem to be applying enough reseeding in the areas that count. It is reseeding the entire FLIP tank, where I'm really only needing the detail in the splash.


Current train of thought:

• Create group of particles that are above the waterline (my current method isn't great, as it groups all points above P.y 0.01)
  
• Apply reseeding only to that group.
  

I'm stuck on reseeding only that group. I see the Reseed attribute name is ‘oversampling’ and ‘oversamplingbandwidth’ but I'm unsure how to edit those in a pop wrangle, or where to place the pop wrangle. Before or after the FLIP Solver?

Have had a search around online and have found one person talking about this, but not how to impliment it.

Any help is greatly appreciated!

File attached of where I'm up to.

I found this parameter on the Flip Solver. Can this be used to define a specific area to be reseeded?

Maybe this will help you

Hi zuoyuanle, I've seen this particular video before but there is no information on reseeding at all.
