Hey there,
has anyone of you succesfully used the free outflow boundary condition while simulating precipitation in MIKE 21 FM? I think it was first introduced in MIKE 2019.
When I use this boundary condition my models usually shows blow ups, hundreds of CFL-Errors etc. while the model runs ok when using a land boundary.
Quote from the manual:
[quote]The free outflow condition is typically used at downstream boundaries where the water is flowing out of the model. In case of water flowing into the model domain the simulation may become unstable.[/quote]
What means "(...) in case of water flowing into the model (...)"?
Thanks
