Random Uniform Waves Showing in Post Processing
 

Hi all,

I am currently having an issue when running boat hulls using interfoam. When I run the simulations at any speed with any hull as the simulation progresses I appear to get these random uniform waves/crests across the entire water/air boundary and I cannot for the life of me figure out why. They are causing issues as it means that I cannot assess the wake properly.

See attached image

Could anyone off me some advice?
