open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear all,

I have quick question and I hope someone can help me. Is there a way to have an output of the flow acceleration in TELEMAC-2D? I am able to save the velocity vectors, the scalar velocity, and other variables in the results file, but I do not know how to save the flow acceleration (either vectors or scalar).
Could anybody help me with this?

Hello

The acceleration is not a standard output variable for Telemac. However, you can add it as an output variable using private variables offered by Telemac for users.
To do that, you need to edit subroutines NOMVAR_TELEMAC2D.f and PRERES_TELEMAC2D.f (in folder sources/telemac2d).
Please see section 14.4 of the user manual (section: adding new variables) to have more explanations.
Moreover, you can find an example of implementation (ready to use) in the fortran file of example "dambreak" (folder examples/telemac2d).
Finally, be careful when you will estimate your acceleration in order to respect the time discretization scheme (based on semi-implicitation, Theta-scheme).

I hope that this helps.
