Software developments

Improvements in the FRESHKISS3D code

Participants : Marie-Odile Bristeau, Jacques Sainte-Marie, Fabien Souillé.

Several tasks have been achieved in the FRESHKISS3D software:

Reworked unittests and basic continuous integration
Optimized IO functions
Added compatibility with new mesh format
Added generic run script that only takes yaml data as input
Added validation cases and new example scripts
Added paraview integrated post-processing scripts
Reworked API and online documentation with sphinx
Simplified dependencies and upgraded python to 3.6
Worked on new numerical schemes:
- Added implicit scheme for vertical exchanges terms
- Reworked vertical viscosity scheme
- Added new fluxes computations
- Fixed vrious bugs (second order, viscosity, water state law)
- Added vertical settling scheme on tracer (suspension models)
Added 3D interpolator
Added lagrangian particle tracking with reflexions on boundaries
C++ Non-hydrostatic code (Nora) converted in cython (80%)
Developement of a « Vilaine » package designed for SAUR/IAV/ANGE project

Numerical simulation of Free Surface Navier Stokes equations with Telemac 3D

Participants : Emmanuel Audusse, Nicole Goutal.

In collaboration with P. Quemar, A. Decoene, O. Lafitte, A. Leroy, C.T. Phan.

This work takes place in a joint project with EDF-LNHE (Laboratoire national d'hydraulique et d'environnement). The aim of the project is to understand the limitation of the actual numerical solution of the free surface Navier Stokes equations with software TELEMAC 3D and to propose new ways to handle important points as the advective part, the divergence free constraint, the coupling between velocity and hydrostatic pressure or the boundary conditions. A study of the mild-slope equation is also performed in order to obtain comparison solutions.
