Deepti is on a distinguished road
i am working on the mesh generation of a 2d falling box. i recreated the mesh. during the running of the program i find that the interface between air and water is fuzzy. this happens even at the start of the run. can u let me know how to get a sharp interface(atleast during the first few iteration)?
