New default choice for keyword TREATMENT OF NEGATIVE DEPTHS = 2 in 2D + 3D
Old default value for TREATMENT OF NEGATIVE DEPTHS is 1 = smoothing which may keep negative water depths. Change of the default value to flux control (option 2) to ensure positive depth by limiting flux in TELEMAC-2D and TELEMAC-3D.
As this choice (or choice 3 in TELEMAC-2D) implies specific options, these options are automatically set to the expected values when using this choice of flux control with keyword TREATMENT OF NEGATIVE DEPTHS. A warning message is written in the listing telling these values are automatically set after using TREATMENT OF NEGATIVE DEPTHS = 2 or 3:
- mass-lumping for water depth (2D + 3D),
- no upwinding for water depth in 2D,
- continuity correction solved at open boundaries in 2D.
