open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi all,

I unfortunately missed out on the 2022 TELEMAC users conference in Paris-Saclay, for which it was announced there would be a workshop on using QGIS with the TELEMAC system. I'm curious to know if any materials (slide decks, files, manuals, etc.) were generated for the workshop? The conference proceedings don't seem to mention anything relevant, and the closest match in HENRY is Pat Prodanovic's 2015 paper which is probably not the most up-to-date.

Specifically, I am looking for more info on mesh generation and bathymetry interpolation for the preprocessing phase. How usable is QGIS, with or without plugins, for this task?

Thanks,
André Renault

Hi André,
hi everyone,

very good topic!

I'm also curious in using QGIS more integrated, especially since the mesh capabilities were added.
Most of the time I'm still using BlueKenue. In recent time I spend quite some work on different paths for mesh generation which weren't really satisfying until now.
Some people reported about using gmsh itself during this year's user conference. Additionally I also tried to get familiar with the .med concept but didn't get really far with that.
I tried the gmsh-plugin in qgis, which worked quite well on a windows machine but I didn't manage to get useful .slf files and boundary conditions.

Another thing I found is the qmesh3 project by Jon Hill. I had quite some correspondence with him in using gmsh as a baseline and generating .med files. But, like I said didn't really got a understanding how to proceed with the .med files.

The last thing I'm currently trying to get into is the pputils, however even there I run into problems converting .msh files into the adcirc format to follow the manual. I did send Pat an email about this.

The next thing I found in the forum was the Lekan Project. I'll try and have a go on this. However, this might be a more up-to-date solution compared to BlueKenue but it'll be nice if there are more hints and experience from other users on how to robustly generate meshes, bathymetry interpolations and boundary condition.

Best regards
Tim
