I thought this may be a meshing issue so I made a model with an ultra fine mesh but it did not resolve it. The mesh is uniform throughtout (each element is the exact same size) and all nodes are merged. It also consists of an upper air portion not pictured. The model makes waves as expected however the initial noise in the water disrupts it. Does anyone know why this is occuring?
