open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear all,

I am doing some investigations on mesh resolutions and resamplings on the Toce Test Case, a test case from a physical experiment regarding the interaction of building blocks in a flood wave (as in: www.mdpi.com/2073-4441/11/9/1840), and am currently optimizing the model setup.

When deciding for a scheme for the advection, I think I stumbled upon some inconsistencies in the telemac user manual:

- In section 7.2.1 "Numerical schemes in Finite Elements", the following schemes are recommended for tidal flats: "1;5;4 or 4;5;4 when there are no dry zones, and 1;5;14 or 14;5;14 when there are tidal flats. For dam break studies option 14;5 is recommended."

- In the section for Tidal Flats (7.5), however, schemes 13, 14, 4, 5, or 15 are recommended.

The validation test case "dambreak" gives a valuable comparison of the different schemes (also using FV), but I think it is a bit confusing that different schemes are suggested within the user manual, especially that the method of characteristics is recommended in one section and not in the other.

Am I missing some points here or would it make sense to elaborate/change some details in the user manual?

Kind regards
Frederik

Hello Frederik,

The writing of the TELEMAC-2D user manuals was done by several people and not at the same time. There may be inconsistencies.

We will have a look to try to remove them if possible.

Hello Frererik,

FYI, I have just tried to solve the inconsistencies you pointed. You will be able to read them in next release 9.0 (coming soon!).

Thanks for your feedback.
