Is it possible to use the DD boundaries in the 3D mode? <br />Untill now I had just one grid and now I thought about splitting the harbour and the river from each other to just refine the interesting grid part of the harbour, cause I urgently need to reduce the running time.<br /><br />If I would have 2 grids, do I also need to have f.e. 2 boundary condition files/bathymetrie/roughness etc??<br /><br />I would be very pleased if anyone could help and share the experiences.<br /><br />Thanks in advance.<br />ManuManuela König2017-04-25T14:55:53Z
