Hi there, On pp.53~56 in the user's manual of BOUSS2D, a demonstration of wave-current interaction was showed. It stated that " a 2-D hydrodynamic model was run to provide the current field for use in the wave model simulations". In my case, i generated the current field byM2D module, which was then included in the simulation of BOUSS2D. But, it seems that the coordinate system was not consistent in these models. So, wrong solution was found. Can anybody tell me how to do that in a right way?
