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.

I am learning MOHID studio 2016. Running SWAN EXAMPLE; MOHID Breakwater, the simulation stops.

Running sediment module in sigle precision
Module sediment err 1
Please use double precision MOHID executable

How can I get DP exe?. How can I install it?
