open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,

When The key word 'Banc decouvrant' is yes, the dry situation will be taken into account. I want to know how this key word works, does it exist the file which has stocken the codes , please?

Hello,

There is not one single file where the tidal flats are taken into account, it is much more complex than that. Basically specific programming due to tidal flats can be seen everywhere with tests like IF(OPTBAN.EQ.1)... or IF(OPTBAN.EQ.2). Option 2 is just a masking of elements (contributions of dry elements are cancelled) but it is not recommended. In Option OPTION FOR THE TREATMENT OF TIDAL FLATS = 1 + option : TREATMENT OF NEGATIVE ZONES = 2, basic properties are ensured : mass conservation, positivity of depth.
Examples of important subroutines for dry zones are:

DECVRT and FRICTI (library telemac-2D)
POSITIVE_DEPTHS (library bief)

With best regards,
