New telemac2d features for v5p4 links from [[:new_version_features|New version features]] \\ ===== v5p4 TELEMAC-2D ===== Date: 3rd June 2004 The principal features of this version v5p4 of TELEMAC-2D are: * Kinetic scheme modified with a different (and automatic) time-step for the tracer. * A new option in parameter estimation. * Internal coupling with Sisyphe. ===== New or modified key-words ===== == TREATMENT OF THE LINEAR SYSTEM (TRAITEMENT DU SYSTEME LINEAIRE) == : Integer. The default value is 1 :The pseudo-wave equation technique has been improved, with an implicitation of the diagonal terms of the diffusion matrix in the velocity equation. This enables larger time-steps (see e.g. culm test-case). :Is thus now important. It was set to 0 in previous versions in the case of pseudo-wave equation. This coefficient must now be set to 0 by the user to have a compatibility with previous versions, otherwise the default value is 1. It is used, when the wave equation is chosen, only for the diagonal terms of the diffusion matrix. == SISYPHE STEERING FILE (FICHIER DES PARAMETRES DE SISYPHE) == :Character string. The default is the empty string ' ' :Goes with key-word **COUPLING WITH** (COUPLAGE AVEC) when **INTER-SISYPHE** (internal coupling) is chosen. :The perl scripts need to know this parameter file. == IDENTIFICATION METHOD (METHODE D’IDENTIFICATION) == :Integer. The default value is 1 :0 is now used for performing a list of tests with prescribed values of friction, to be used by techniques which do not require an adjoint system. :The values are given in file : **FORMATTED DATA FILE 1** (FICHIER DE DONNEES FORMATE 1) with a first line of comments and then for every line, iteration number followed by friction coefficients for every zone (free format) :The result for every test is given in the **FORMATTED RESULTS FILE** (FICHIER DE RESULTATS FORMATE) :It can be read by Rubens by selecting format **SCOPT** ===== New user subroutine and modifications in user subroutines ===== == SUBROUTINE UTIMP_TELEMAC2D == : Called when outputting the results in listing and results files. The user may add special outputs in this subroutine.
