Take into account the friction coefficient along the walls #3

Closed xavierdechamps closed 2 years ago

xavierdechamps commented 2 years ago

For the moment the friction coefficient is only taken into account at the bottom of the bed. Along the walls the flow is supposed inviscid on the vertical section. For a better matching with experimental data it is better to include the friction on the vertical section of the wall as well. Consider the possibility to have a friction coefficient different between the bottom and the vertical section.

The inclusion of the wall friction has been implemented and pushed to the main branch in commit a0d4b7c0ec7850beacc1123eff540d7c368f207b. The user must had a new line in the parameter file 0.0 : Manning roughness coefficient (wall)
