Twin experiment This model was created from a very similar example, but with domain-decomposition added. The results should be the came as for that experiment. Note that domain-decomposition does not work for delft3d version 4 on linux. 1D-channel - grid 200x3 dx=500m L=100km - - 10min timestep - initial wl 1m - observations 66,132,198 truth: - 1-jan-1991 to 17-1-1991 -
