Feature log
New features for all programs version 7.3
- all modules: FORTRAN FILE can be a folder that contains several files, not a single file (but still possible)
- TELEMAC-2D/TELEMAC-3D: fix the culvert formulation 1 so that it falls back to the siphon formulation in that specific case.
- TELEMAC-2D/TELEMAC-3D: sources can also be assigned with global node numbers
- TELEMAC-2D/TELEMAC-3D: Lambert 93 projection when modelling tide.
- TELEMAC-2D/TELEMAC-3D: Adding 7 extra harmonic constituents, for FES2014 tidal database (M3, M8, Msf, N4, S1, Sa, SSa).
- TELEMAC-3D: remove the option DIFFUS. This option was meant to remove the diffusion but it actually did not remove the diffusion on U,V. Besides, it could happen that when using DIFFUS=NO the source terms were not included in W and the tracers. We thus chose to remove this option altogether. From now on, to disable the diffusion the user can only set a zero diffusion coefficient.
- TELEMAC-3D: remove the option OPTDIF to keep only one formulation (OPTDIF could take the values 1 or 2 but the option 2 did not seem to bring improvements compared to the option 1. It was was not used in any test-case, neither documented so we only kept the option 1 in the code)
- TELEMAC-3D: modular CONDIM and BORD3D subroutines (initial conditions and boundary conditions). Simplification of the CONDIM subroutine (initial conditions + mesh transformation), now split into several subroutines which do various and separated treatments (e.g. initial conditions for water depths, velocities, tracers... or mesh transformation different from the classical sigma transformation). The user only needs to fill one short file per variable. No need to keep the whole CONDIM subroutine. For BORD3D, every specific treatment is implemented in a separate subroutine USER_BORD3D called by BORD3D (see examples to fill).
- ARTEMIS: Creation of free surface elevation (time/space varying) files.
- ARTEMIS: Removing the need to code within BORH (using LECLIM and the BOUNDARY CONDITION FILE instead).
- ARTEMIS: Automated calculation of the phase for incident boundaries (in PHBOR), starting from the "node of attack" of the offshore wave, iteratively computed along both sides away from the attack node along the rest of the incident boundary.
- STBTEL: Now refining the boundary conditions as well as the mesh Available through the script convertert.py as well
- Addons: Adding vim-syntax for .cas and .dico files
- TELEMAC-2D: change computation of wall distance (used in Spalart-Allmaras turbulence model). The wall distance(WDIST) is now computed in parallel with a laplacian operator.
- TELEMAC-2D: new framework for automatic convergence studies
- TELEMAC-3D: coupling with the water quality library AED2.
- TOMAWAC: Automatic imposed spectrum on nested mesh.
- TOMAWAC: In order to better take into account boundary conditions Limwac is called at the end of the loop in time instead of beginning.
- TELEMAC-2D: I/O criteria of result file now homogenous with FE or FV (steered by time-step and period for graphic output)
- TELEMAC-2D: Activation of source terms for FV (Mass and Momentum): so far only partially implemented for mass source terms.
- TELEMAC-2D: New turbulence model (Spalart-Allmaras)

New features of SISYPHE version 7.2
New features and differences with version 7.1
Release date: end 2016
Latest article update: 03/01/2017
New features
Correction of the subroutine(s) solving bedload transport processes. This modification aims at improving the numerical results where wetting and drying processes are present. A new keyword is proposed : MINIMUM DEPTH FOR BEDLOAD. The default value for this keyword is 1.0E-2 m (new variable HMIN_BEDLOAD). This value can be modified by the user: as a guideline and after some discussions and testing, we can suggest a value in the range [2-3]\times d_50, being d_50 the median sediment diameter.
Efficient and precise computation of sediment fluxes through a section. New keywords: FLUXLINE, FLUXLINE INPUT FILE.
The module DREDGESIM has been replaced by NESTOR, a new module capable to simulate sediment fate and dredging scenarios.
A liquid boundary file can be specified for bedload discharge.
Improvements in the computation of the angle alpha (sediment direction) for multiclass sediment distribution.
Corrections of stability issues for the sediment slide option.
Security check for the initial definition of layers (init_compo.f)
Documentation
A brand new LaTeX documentation for Sisyphe is provided in folder documentation.
New features of Telemac-3D version 7.2
New features and differences with version 7.1
Estimated release date: end 2016
Latest article update: 31/08/2016
Main new features of this version 7.2
New and less diffusive distributive advection schemes (as in Telemac-2D version 7.1)
K-epsilon model turbulence model can now be used independently on the horizontal and on the vertical
Culvert modelling as in TELEMAC-2D + new formulation for culverts in TELEMAC-2D and 3D, proposed and tested at Flanders Hydraulics
New or modified keywords
"VELOCITIES OF THE SOURCES ALONG..." (VITESSES DES SOURCES SELON...)
Final S in French for VITESSE (homogeneous with the English keyword + TELEMAC-2D.
"SCHEME OPTION FOR ADVECTION OF VELOCITIES" (OPTION DU SCHEMA POUR LA CONVECTION DES VITESSES)
"SCHEME OPTION FOR ADVECTION OF K-EPSILON" (OPTION DU SCHEMA POUR LA CONVECTION DU K-EPSILON)
"SCHEME OPTION FOR ADVECTION OF TRACERS" (OPTION DU SCHEMA POUR LA CONVECTION DES TRACEURS)
One value per tracer can be given.
When Leo Postma, N or PSI advection schemes are chosen (3, 4 or 5). The following options can be now selected:
1: normal Leo Postma N or PSI (like previous versions),
2: predictor-corrector (see proceedings of User Club 2014),
3: second order predictor-corrector,
4: LIPS scheme (Locally Implicit Psi Scheme).
These 3 keywords can also be used to decide whether the method of characteristics will be strong (1) or weak (2).
For options 2, 3 and 4 the following keyword can also be used:
"NUMBER OF CORRECTIONS OF DISTRIBUTIVE SCHEMES" (NOMBRE DE CORRECTIONS DES SCHEMAS DISTRIBUTIFS)
The default value is 1 (one value for all tracers only). Can be 2, 3, after will probably not be very efficient. Gives less numerical diffusion.
Two other schemes: LIPS and ERIA, meant for dry zones, are still under development and are scheduled for version 7.2.
For more details see post #19861 in the forum (Generalities/Announcements...).
"NUMBER OF SUB-STEPS OF DISTRIBUTIVE SCHEMES" (NOMBRE DE SOUS-PAS DES SCHEMAS DISTRIBUTIFS)
Only for implicit scheme with predictor-corrector.
"CONTINUITY CORRECTION ON OPEN BOUNDARIES" (CORRECTION DE CONTINUITE SUR FRONTIERES OUVERTES)
Changes the free velocities on open boundaries to get a better divergence-free field.
"CULVERTS DATA FILE" (FICHIER DE DONNEES DES BUSES)
Description of culverts/bridges existing in the model.
"NUMBER OF CULVERTS" (NOMBRE DE BUSES)
Number of culverts, tubes or bridges treated as source terms. They must be described as sources in the domain and their features are given in the CULVERTS DATA FILE.
"OPTION FOR CULVERTS" (OPTION POUR LES BUSES)
Option for the treatment of culverts. There are two options in TELEMAC.
