## 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)
