Latest release - v6p3r2

Following the plan of our new release cycle (i.e. more frequent intermediate releases between major releases), the new version v6p3 release2 is now available. Here is a short summary of the main changes since v6p3r1:

  • Improvements to the automated validation of the system in parallel mode
  • Overall memory and speed optimisation of the python scripts
  • Allowing multiple CAS files to be run together as one HPC (parallel) job
  • An important correction to the PSI scheme,
  • An important correction to the computation of pressure gradients in the wave equation
  • A new example added to CORRXY (in comment),
  • Implementation of stability criteria for finite volume schemes
  • Improvements to the configuration file and its management of parallel simulation
  • And various bug fixes and improvements following your feedback on the forum (e.g. better captures of errors in the python scripts)

This intermediate release is available through our SVN:

Thanks to all the contributors to this version and to all the users that provided very useful feedback. As usual, your comments and suggestions are welcome on the forum.

Fudaa-Mascaret v3.1.9 available

Version 3.1.9 of Mascaret with the Fudaa user interface is now available for download.

Here are some of the new features and bug corrections:

  • Update of the Java compatibility (older versions were compatible with Java 1.6, now Java 1.7 is the minimum required)
  • Update of the calculation engine (API improvements and bug correction in the Tracer module)
  • 100% compatible GNU/Linux
  • Bug correction for reading Rubens file format on a 64-bit architecture
  • Pre-processing improvements (laws import is automated during the .cas file import, possibility to visualise upstream and downstream cross sections as overlay in the cross section editor)
  • Post-processing improvements (animation of water level on a section with possibility to record videos, possibility to modify the time scale)

The new version can be downloaded in the installation download area.

Version v6p3 released

The v6p3 version is officially released today.

New functionalities

Some of the key new features of this version are:

  • Internal coupling waves-currents and sediment transport;
  • TOMAWAC is now fully compatible with parallel processing;
  • Drogues or floating bodies now work in parallel in TELEMAC-2D and 3D.

Many other new features are available, for the full set of changes since v6p2 see the feature log.

New module

The new DREDGESIM module (now called NESTOR) has been integrated in the system. DREGESIM has been developed by the University of the German Federal Armed Forces in Munich on behalf of BAW, and as its name indicates, is used for modelling of dredging.
A description of all available modules is provided on this page.

Automatic installer

In order to help with the installation of the system, we have created an automatic installer for Windows that will install the TELEMAC system and all the other required software (compiler, python, svn...), and configure the whole. The installer now automatically installs the system in parralel. A version for Linux is planned for the future

 

New code structure

We have modified the structure of the former TELEMAC system to help with the coming merge with the MASCARET system. It also follows structures of other known open source software, and makes the tree more logical and easier to understand. You can find details on the TELEMAC source code structure on the source code wiki page.

Updated release policy

Rather than only creating a yearly tag "v6p3" (read-only snapshot of the development trunk), we have created a branch called "v6p3", which allows us to fix bugs over its life span (if there are any). As a result, the branch "v6p3" is a moving target.

For users who need a fixed release, particularly for quality control procedures in consultancy studies, we will also be creating tags "v6p3r0" (release 0), "v6p3r1" (release 1) etc., to keep up with the branch "v6p3". These tags will be created on a monthly basis or as necessary depending on the number of changes made to the branch "v6p3". Finally, you will note that the first (v6p3r0) was release early August and that following the feedback of a few enthusiasts, we have now created v6p3r1. This tag is our stable version for v6p3.

New version 6.2

Version 6.2 of the TELEMAC system is now available. Here is a preview of the novelties of this important new release:

  • Tidal boundary conditions have been extended to Telemac-3D, and to model TPXO.
  • Open boundary conditions with Thompson method has been extended to Telemac-3D.
  • A full port-folio of test-cases for Artemis.
  • New possibilities of boundary conditions in Sisyphe, and improved mass-balance information, plus a new concept for sediment layers.
  • A more efficient module for the method of characteristics in parallel.
  • In Telemac-2D: tracer decay, culverts and weirs simplified, breaches now available, new finite volumes algorithms, rain and evaporation, Okada model for generating tsunamis...

All test cases have been sucessfully run on several platforms: Windows, Linux, Unix, and with several compilers: Intel, gfortran, g95, Nag, HP, etc.

The Python scripts have been largely extended.

You may also refer to the feature log page to have more insight on the novelties.

Last but not least: the 1D MASCARET is now also available for download on this site. The two codes will be fully merged on the SVN repository by the next release. Issues, feedback and suggestions can be discussed in the MASCARET forum.

We thank all the developers who contributed developments, all users who made constructive remarks, and we hope you will enjoy this new version.
