The mesh deformation models the movement of the barges with the rising water level. I am modelling a set of water locks that slowly fill with a set of barges inside. (See attached pictures) Problem is that the turbulence equations keep diverging. Ensuring high-quality and robust implementation of core turbulence and computational aeroacoustics models in Simcenter STAR-CCM+ Supporting maintenance of our existing capabilities (bug fixing, code refactoring. I have a transient multiphase simulation with mesh deformation.
