I have a flattank fluid extended scene where the outer edges of the ocean plane are bending up about every 3rd rendered frame. See attached images. I am only a few months into Houdini, so I'm still new (excuses). Does anyone have any ideas as to what might cause this?

Here is the particlefluidsurface node if this helps

It appears that if you reduce the particlefluidsurface node “Region Voxel Scale” it fixes this issue. I had it set at 4. After reducing it to 1 the ocean plane flattened out.

Attached are a couple of images showing the ocean plane bent up and then flattened out.

I don't understand why that fixed this issue. I will have to do more reading through the docs. If anyone knows I would love to hear what you think.

Thanks.
