Crash at the begining of the usteady flow simulation

Crash at the begining of the usteady flow simulation

(OP)
Hello, I am Romuald and I am looking for advices with unsteady flow simulation.

Here is my problem. I am runing my first unsteady flow simulation but it crashes right at the begining of the unsteady flow simulation. The only error message is (+STOP! Error in the time window). I really don't understand what the problem could be as the begining of the simulation fits with the begining of the flow hydrograph. I simplified my geometry data so there is no bridge or storage or anything and I put a initial flowrate to avoid the channel to go dry.

Thanks for any comments and possibilities of error made at this step.

Regards.

Sorry, I forgot to write that my question is about HEC-RAS.

RE: Crash at the begining of the usteady flow simulation

I am facing exactly the same problem with HEC-RAS..Even when I used the examples provided by the software, still I get the same error when doing unsteady analysis..Please Help!

Hello RickMon,

I found a response to the problem, so it could probably help you.

It comes from the date format in windows vista (or whatever). Mine was in french so I just had to switch it to english in the control panel, and then everything works finely.

I had a probem quite similar when rasmapper chrashed because of german typo (Umlaut). HEC-RAS is not a commercial software so there is very little effort made with compatibility.

Hi RomCu

Thanks for the feedback, it was the same problem as yours...Now it worked fine...Thank you very much, you are a life saver :)
