open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear TELEMAC users/moderators,

When simulating dam breach flow routing using TELEMAC-2D is there a CAS file flag (or BlueKenue process) to extract flood-wave arrival time throughout the domain (e.g., time to 1 meter of depth at all nodes)? Wanted to inquire before writing a user-defined function. Any help or clarification would be greatly appreciated.

Thank you,
Chris

Hi Chris,

There's nothing in Blue Kenue.
This is the kind of task where the python interface is most appropriate.

Cheers... Martin

Hello,

it is some time ago and I don't remember if it worked well but you can try the class crunchSELAFIN which has a function named "calcPeakTimeModuloM2" in runselafin.py which is in the scripts/python27 directory.
You can invoke the function in this way:
python runselafin.py crunch -v TIME_OF_PEAK input.slf output.slf
The default output time is in hours but you can change it to your needs in the line: vari[0][ipoin] = ( (ti-t0)/3600.0 )%12.42.


Hope this helps,
Clemens

Hi Chris

In telemac, you could extract the maximum of free surface and velocities with the time of this maximum (see in the variables for graphic printout).

There is no existing option to save the flood arrival time but it's not really complex to add in preres_telemac2d with the private variable.

You could also make a post processing analysis of the result to compute this result (with the method of Clemens for example). In this case, the precision of the result depends on the result period...

regards
