I recently found your suit of tools which I deem superb.
I am training with morpho2DH, and the problem I am dealing with, focuses on
a debris flow on a hillslope, feeding at the bottom of the slope a high flow rate mountain creek (a sort of T geometry).
I made some tests with no luck, adding an inflow as to model the creek, but the solution seems to go NaN as the inflow starts.
Furthermore, to make sure I didn’t misunderstand the capabilities of Nays2DH: it models most of the processes of morpho2DH but not debris/mud flows? Am I right?
Thank you for any help or explanation you might give
