cut density inside dop

[gangland]

Hey guys.

I building an underwater scene. In dop I using high buoyancy values.

i would like to delete the velocity and density field right above the water surface directly in dop. it would improve to memory consumption. Also cut the velocity field(in the surface of sea) that in future would advect points.

i not figuring how to do that, can anyone help me?

you can do that with a gaswrangle node inside DOPs

// using height as threshold
if(@P.y>chf("max_Y_value")){
	f@density = 0;
  	v@vel = 0;
}
// or anthing outside the water area
if(f@surface>0){
	f@density = 0;
  	v@vel = 0;
}
