Telemac-2D version 7.0
Estimated release date: end 2014
Latest article update: 29/04/2014
Main new features of this version 7.0
* Stage-discharge curves Q(Z) now programmed.
* New predictor-corrector PSI scheme for advection (as a variant of PSI scheme)
New or modified key-words
"WAVE DRIVEN CURRENTS"
(COURANTS DE HOULE)
Wave driven currents may now be set to .FALSE. with a coupling with Tomawac. In that case it is a one way coupling, with no feed-back from Tomawac to Telemac.
"SPATIAL PROJECTION TYPE"
(TYPE DE PROJECTION SPATIALE)
!!!!!!!! The latitude longitude option (3) now expects degrees instead of radians !!!!!!!!
(FICHIER DES ZONES)
This file is used with FRICTION DATA = YES, which needs a FRICTION DATA FILE (giving a law of friction and a friction coefficient), and a file connecting every point to a zone number. This file was previously put in the FORMATTED DATA FILE 1 and has now a specific file. In the final version 7.0 this file will be split at the level of domain decomposition. ZONES FILE has as many lines as points in the mesh, with on every line:
point number zone number
"TYPE OF ADVECTION"
(FORME DE LA CONVECTION)
This keyword is still valid but should be replaced by the following new ones:
SCHEME FOR ADVECTION OF VELOCITIES (SCHEMA POUR LA CONVECTION DES VITESSES)
SCHEME FOR ADVECTION OF TRACERS (SCHEMA POUR LA CONVECTION DES TRACEURS)
SCHEME FOR ADVECTION OF K-EPSILON (SCHEMA POUR LA CONVECTION DU K-EPSILON)
which already exist in 3D. SCHEME FOR ADVECTION OF TRACERS may be an array with a different value for every tracer. SOLVER FOR THE DIFFUSION OF TRACERS may also be an array.
"SCHEME OPTION FOR ADVECTION OF TRACERS" (OPTION DU SCHEMA POUR LA CONVECTION DES TRACEURS)
One value may be given per tracer. When present, this keyword replaces and supersedes SUPG OPTION and OPTION FOR CHARACTERISTICS. For the PSI scheme, option 1 is the classical PSI scheme, option 2 is the new predictor-corrector PSI scheme.
"SCHEME OPTION FOR ADVECTION OF VELOCITIES" (OPTION DU SCHEMA POUR LA CONVECTION DES VITESSES)
As the previous one, but for velocities.
"SCHEME OPTION FOR ADVECTION OF K-EPSILON" (OPTION DU SCHEMA POUR LA CONVECTION DU K-EPSILON)
As the previous one, but for k and epsilon when the k-epsilon turbulence model is chosen (but not all advection schemes are programmed for k-epsilon).
For all the following keywords, one value may now be given per tracer (see examples cone and pildepon) :
"SOLVER FOR DIFFUSION OF TRACERS" (SOLVEUR POUR LA DIFFUSION DES TRACEURS)
"SOLVER OPTION FOR TRACERS DIFFUSION" (OPTION DU SOLVEUR POUR LA DIFFUSION DES TRACEURS)
"MAXIMUM NUMBER OF ITERATIONS FOR DIFFUSION OF TRACERS" (MAXIMUM D'ITERATIONS POUR LA DIFFUSION DES TRACEURS)
"PRECONDITIONING FOR DIFFUSION OF TRACERS" (PRECONDITIONNEMENT POUR LA DIFFUSION DES TRACEURS)
none so far
Modifications in user subroutines or new subroutines
Subroutines incide and celerity have been deleted. The incident wave boundary condition (1 in boundary conditions file) has been suppressed and is replaced by the Thompson boundary condition (keyword OPTION FOR LIQUID BOUNDARIES).
