Appendix : Boundary Conditions¶
Enabled boundary conditions¶
The following table summarizes the boundary conditions recognized by Tolosa-sw. These boundary conditions must be defined in the Gmsh file .geo by creating Physical Groups.
Boundary conditions (BC) | Specifications
-------------------------|---------------
Rigid Wall BC | wall
Neumann BC | neumann
Tide BC (tide.listneeded)| tide: consider all tidal constituents
tide#N: consider only the N first tidal constituents
Discharge constraint BC | q: Read a tabulated file bc_q.txt with discharge values
q#X: Fix a constant discharge at X (m^3 . s^-1)
q#user: Define discharge at the boundary from a function in m_user_data.f90
Height constraint BC | h: Read a tabulated file bc_h.txt with height values
h#X: Fix a constant height at X (m)
h#user: Define height at the boundary from a function in m_user_data.f90
Sea surface height (ssh) constraint BC | ssh: Read a tabulated file bc_ssh.txt with ssh values
ssh#X: Fix a constant ssh at X (m)
ssh#user: Define ssh at the boundary from a function in m_user_data.f90
