open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,

I have a question about the differences between the Perl scripts and the Python scripts. I ran the same simulation using the Perl scripts (v6p1) and the Python scripts (v6p3).

To my surprise the results were quite different. In my simulation, there is a canal composed of two portions: an upstream rectilinear portion and a downstream curvilinear portion. A hydraulic jump forms in a rectilinear portion. Telemac2D v6p1 (Perl scripts) models the hydraulic jump well, with results roughly matching those calculated with a 1D model. However, v6p3 (Python scripts) has trouble converging. After reducing the time step significantly, compared to that used with v6p1, the results are still unstable with v6p3.

I realize that I am using quite older versions of Telemac2D, but I was wondering if anyone knows if the Perl scripts are generally more stable than the Python scripts? I think I remember reading that somewhere in the documentation…but I may be wrong! Or could it be an issue with Telemac v6p3 that has been corrected in the later versions?

I am a bit concerned with this because I saw that the Perl scripts will probably be phased out in the next versions of Telemac.

Thank you!

Hi,

This was a bug in v6p3. It was corrected afterward.
The results are the same with Perl and Python now.
And indeed the Perl scripts were removed in v7p2.
