Hello guys, can anyone point me in the right direction on how to use Surface Tension Blur inside the FLIP solver?

I cannot find anything referring to it online, except for a brief mention in the Houdini Fluids Master Class. I guess its a mask that lets you control which area of the fluid the surface tension is applied to, but I cannot figure it out..

Thank you for helping!

Surface tension blur is just for blurring the effect of surface tension force, not to directly control it's strength

to control strength of surface tension non-uniformly you can modify field called surfacepressure using any microsolvers plugged into Volume Velocity input
