Can you post the Model.dat input data file please?

You can find that executable in MOHID 4-9-2 installation folder:

\"C:\\Program Files\\MOHID\\\"

(it may be different if the Windows language is not English)

In MOHID GUI, go to Tools -> Options -> Executables and change the path of the MOHID Water executable with the Double Precision one.

Hello Luis

My model.dat is
START : 2011 0 1 0 0 0
END : 2011 1 1 6 0 0
DT : 0.1
SPLITTING : Double_Splitting

But I have to tell you that i alredy solve the error with a low DT because my gird discretization is so fine. And also found the .exe in Mohid 4.9
