Error in Unsteady results

Hello:

First, sorry for my English, I can read it but I'm very bad writting it.

My problem, I'm working in Unsteady flow with HEC-RAS, and I intruduced a flow hidrograph as boundary condition. This flow hidrograph has as Qmax 24 m3/s.

I runned the model and the results are Q in the order of 24000 m3/s. I look at Unit System and my configuration of the computer, but I think that all is correct.

Someone could know what can it be happening?

Thank a lot,

Jorge Rodríguez

Just curious, are the "J" and the "g" in your name both silent?

I had this same problem because used low hidrographs... then I prove with flow in order of 50-100 m3/s, and with a constant hidrograph, eg. all time with 50.
You can send me your model, maybe i can help you
my mail is zulypv@yahoo.com
good luck

Estimado Jorge,

yo también tengo problemas con el inglés así que te escribo en español. ¿Puedes comentar más detalles de la simulación? Amí nunca me ha pasado que me multiplique por mil el caudal. Lo que me ha pasado es al revés, que a lo largo de la simulación me desaparezca caudal: hay que tener cuidado con ese detalle.

Hola, Luis

gracias por tu contestación, ya resolví el asunto, tenía que ver con lo reducido de mis caudales y con las tolerancias de cálculo (demasiado holgadas las tenía en un principio).

mil gracias de nuevo!
