Particles sinking when using velocity scale (oceantoolkit)

Hey Folks,

My ultimate goal is to create a larger amount of splash from an object moving at a slower pace.

Using the ocean toolkit wavetank, I set up an example and adjusted the “velocity scale” in the flip solver. The splash being generated is the effect I'm looking for. However, increasing velocity scale seems to cause the particles to sink and cause holes. Is there a way around this issue?.

Check the attached qt and h15 file

It appears as though the boundary layer is actually the source of this problem. If the flip sim is not travelling with the object, the boundary layer is not needed and the problem would never be visible.

I do need to move the flip sim along with the object and turning off the boundary layer will create problems with the sim as well.

Did anyone else run into this problem before?

Please check the attached flipbook, both sims are using velocity scale 20, the one with particles sinking has the boundary layer enabled.
