Adding boundary conditions on the bed for Telemac-3D simulations

Abstract : Telemac-3D has been developed to work on a two dimensional mesh that has been extruded along the z-axis. Ongoing work is done by the development team to move away from this structure. The work presented here, and available in version 7.1 of Telemac-3D, is the first step of this process as it will extend the available external boundary conditions to the bed. The impact of imposing a flow rate on the bed on the equations solved by Telemac-3D and on the hypotheses chosen will be developed. The use of these new boundary conditions in a Telemac-3D simulation will then be explained. These boundary conditions will then be illustrated through a simple test case through a comparison with source terms, which was the only available method in the previous versions of Telemac-3D to model inflow near the bed.
