open TELEMAC-MASCARET The mathematically superior suite of solvers

i was trying to run simulation in sisyphe without coupling with telemac-2d from results velocity UV, free surface elevation,water depth and scalar velocity that i got from telemac2d simulation. the sisyphe simulation was fine before, then i changed STEADY CASE= NO, it gave the following error.

someone know the reason and how to fix it...?

Hello Safu,

I would like to see your steering file for Sisyphe. It looks like something is missing there.
Furthermore, do you have bottom in your hydrodynamics file? That is an important variable for Sisyphe (although it is fixed).

Cheers,

José Andrés.

i have included water depth in hydrodynamic file

Hello,
I bet you have a typo in your T2D steering file...

pablo

here is my sisyphe steering

Safu,

i believe the error is in the time step.
What is the time step and MUMBER OF TIME STEPS of your hidrodynamic simulation?

can you send the hidrodynamic steering?

other possibility is that your hidrodynamic simulations was saved/finished with some error. Is it possible to open it in bluekenue? can you change correctly the time steps in BK ?

and also delete this line in your steering file:
STEERING FILE ='steering_sisy_4.cas'

and try again.

hi ekirinus,

here is the hydrodynamic steering file

Safu,

When running SISYPHE with a hydrodynamics result file, the time step needs to be equal to the time step in the results file. In your case that is 100 x 2 s =200s, whereas you are using 2s. You can reduce the calculations time step using the key word. Also, going on the cas file, your hydrodynamic file will start at t =200s, whereas you are trying to start your SISYPHE run at t =0.

NUMBER OF SUBITERATIONS


However, do consider running TELEMAC and SISYPHE coupled. Simultaneous computations are for more accurate than running SISYPHE from a hydrodynamics file. And it is far easier to set up as well.

Good luck,

Michiel
