open TELEMAC-MASCARET The mathematically superior suite of solvers

Hey everybody,

I'm writing my Bachelor Thesis right now and have a problem with running a Telemac2d simulation. I'm an absolute beginner so please excuse if this is a stupid question.
I used the latest version of FUDAA-PREPRO (1.3.0-RC8) to generate and edit the .cas-file and I tried to run the simulation with the version v7p0 of TELEMAC-MASCARET (automatic installer).
During the first Iteration Step the simulation stops and the error: "Fortran runtime error: End of file" occurs.
I read many forum articles but still I have no idea what the problem could be.
Does anyone has an idea to solve my problem? I attached the .cas-file and the error message of the console.
Thanks a lot!

Hi
As it's indicated, you reach the end of the liquid boundary file.
Check it to be sure that the time in it is higher than 7200

Hello,

As the time step is 7200 s (it is very high...) and 12 time steps are asked, it is even 7200*12 s that should be covered by the file. You can even put a slightly longer time in the file to prevent any problem of truncation error that would trigger reading an extra line.

Thank you for the hints!
FUDAA-PREPEO created the liquid boundary file by itfelf and as I see now it is empty. Do I need the file at all when I just want to discribe the inflow (flowrate m^3/s) and outflow (flowrate m^3/s, elevation m) boundary conditions that are constant in time? Is it possible just to discribe them with keywords (PRESCRIBED FLOWRATE/ELEVATION) and the corresponding changes in the boundary condition file?
The time step is so high because it is an initialization simulation to reach the steady state.

Hello,

Yes in this case you can work with only keywords.

On the large time step : Telemac has no steady state procedure that would yield a steady state when you give an infinite time step (what you have with Newton-Raphson techniques). All flows must be physical, with a time step giving a reasonable Courant number.

With best regards,

Ok I will try this.
Thank you for the hint with the steady state! I'll try to manage it.
Best regards!
