    Hi. I was computing my 2D unsteady model for 5 hours and it turn error in HEC-RAS 6.0 and 6.1. I already use courant, SWE-ELM (original/faster)

    Error with program : RasUnsteady.exe Process count = 24 Exit code = -1073731819

    I’ve been struggling for a day or two. I really don’t know, what’s wrong, since I new to this program. Can you help me.

    Hi Manthani,

    I wonder if you can fix your problem with RasUnsteady.exe, I had solve that problem making sure that the grid size is appropiate with the time step and the Courant condition. Maybe you can show us these parameters of your model.

    Saludos, Mati
