I have some that other users of MIKE 11 have had this error at the moment to run the Simulation. I have tried many alternatives and still I could not solve the problem. I am developing a 1D Model and I am trying to simulate the spillage from the riverbed to the floodplains, with a parallel branch the represent the longitudinal profile, as conceptually is explained in the manual and in different articles. The study area is characterized by flat floodplains, along the river stretch.

I appreciate if someone can give me tips to delineate the floodplains with the branches or can advice me how I can solve this error. If you need additional information, please let me know.
