Add turbulence to flip fluid with boundary layer

[jop]

Hi!

I'm pretty new to houdini's flip fluids and I'm stuck with something.

I have a flip fluid liquid simulation with boundary layer for river like effect. I've setup a boundary velocity field to create the river flow.

Now that I'm trying to add some pop wind in order to add turbulences, it appears that it overrides the boundary velocity effect.

SoI'm looking for a way to blend those two effects.

Any ideas ?

Thanks.
