Jung hoo Member Lee Jung Hoo Join Date: Dec 2015 Posts: 37 Rep Power: 10	Hi, foamers. I'm using olafoam to simulate waves above a structure(a simple mound) like below. As you can see, there exist some weird huge velocities at the start point and end point of the structure even though waves didn't approach the structure yet. The surface is air-water interface(alpha.water=0.5) and the structure was inserted by using snappyHexMesh. Can anyone explain to me why that some noises exist? Thank you in advance.! lourencosm likes this.
