I have been learning some Fluid simulation recently.
When I was using the ocean flat tank, it was all right, but when I started to use the Guided Ocean Layer to simulate, the number of points will get doubled starting from the second frame.

I am using Houdini 16.5.571 version.
Here is a video of one of my tests.

The first frame is not that clear though so I got screenshots.


Is this normal? Does anyone have any idea..(Seems like this one the particle narrow band is turned off though)
