FLOW-3D HYDRO's hybrid 2D/3D modeling capability allows you to incorporate a 2D depth-averaged mesh into your simulation. This capability is helpful for larger domains, such as this simple dam break example that spans 4.5km in the downstream direction. This FLOW-3D HYDRO example uses a nested 3D mesh around the dam and its initial release location, then transitions to a 2D mesh further downstream. In the video, the first simulation is a dam break into a dry channel; the second simulation has the river flowing at the time of the dam break. A hybrid 2D/3D meshing approach can be very helpful in reducing computation time in dam break studies, including non-Newtonian tailings flows, as well as in modeling bridges and culverts.
