Hi,

I'm using flip to show some water feature ideas, so it a couple of metres in scale. I've turned on viscosity just to stop the water moving so quickly but kept the value very low - 0.001, and turned on slip on surface and set the slip scale at .95. Once slip scale goes above about .8 i start getting little pops in the sim. I've checked for interpenetration between the emitter and the obstacle and it seems like there is plenty of space but my flip debugging skills end there sadly…

I assumed that turning viscosity on and keeping it low was appropriate as all liquids must have a viscosity value and I wanted the water to interact more with the surface rather than glide so effortlessly over it.

I've included the hiplc file in case anyone is bored and wants to take a look.


cheers,

Andi.
