TELEMAC (Auto-Installation)

TELEMAC (Auto-Installation)#

Preface#

This tutorial walks you through installing open TELEMAC-MASCARET on Debian Linux and Ubuntu-based systems with automatic installer scripts. Plan for roughly 1-2 hours and a stable internet connection; the downloads exceed 1.4 GB. For detailed installation instructions, go to the detailed TELEMAC installation page.

Requirements#

System packages#

On Debian 12, ask your system administrator to sudo-install the following packages via aptitude:

Note that the automatic installer script might detect additional packages required.

Set up installation paths#

TELEMAC will be downloaded (git-cloned) from its GitLab repository into a directory you choose, and that will be referred to as ROOT directory in the following. Also, SALOME will be downloaded and installed in this ROOT directory. Select one of the following setups:

  • Single user without admin rights: ROOT=/home/<USERNAME>/opt (that is, ROOT=$HOME/opt) (XDG-conformant alternative: ROOT=$HOME/.local)

  • Shared use without root: only if a group-writable location already exists, for example an NFS share like ROOT=/srv/shared/telemac

  • System-wide (admin required) on Debian-based systems: preferred ROOT=/usr/local (binaries in /usr/local/bin, libraries in /usr/local/lib); ROOT=/opt is also acceptable for a self-contained tree

SALOME#

Choosing the right version of SALOME cannot be reasonably automated, so find and download the latest version of SALOME, and save it in the ROOT directory where you want to install Telemac.

  1. Confirm your Linux version:

  • Debian: cat /etc/os-release

  • Mint: lsb_release -a

  • Ubuntu: inxi -Sx (also works on Mint)

  1. Download the SALOME build

  • Go to the official SALOME download form

  • Pick the latest version with the Ubuntu build (that matches the Mint base); or pick the less frequently updated “Linux Universal”

  1. Verify the checksum: from SALOME’s md5 page, fetch the matching .md5 file for your archive and verify locally

  • Example for the 9.15 tarball: md5sum SALOME-9.15.0.tar.gz

  • Compare with “SALOME-9.15.0.tar.gz.md5” from the md5 page - don’t skip this!

Get the installer scripts#

Run installers#

Installation pattern#

Note that you might need admin (sudo) rights for installing additional system packages and that the installation can take a while because the script downloads Telemac. The script installs by default Telemac v9.0.0. To install another version, use the --tag "TAG" option when running the scripts; latest tags can be found at https://gitlab.pam-retd.fr/otm/telemac-mascaret.git.

To run the installer, tap (replace ROOT with your ROOT directory and SALOME-x.xx.xSRC.tar.gz with the name of the SALOME tarball that you downloaded):

cd ROOT
chmod +x telemac_debian12_installer.sh
./telemac_debian12_installer.sh --root "ROOT" --salome-tar "ROOT/SALOME-x.xx.xSRC.tar.gz"

After finishing the installation, the Telemac environment can be loaded as follows:

cd ROOT/telemac-mascaret/configs/
source pysource.debian12.sh

cd ROOT
chmod +x telemac_ubuntu24_installer.sh
./telemac_ubuntu24_installer.sh --root "ROOT" --salome-tar "ROOT/SALOME-x.xx.xSRC.tar.gz"

After finishing the installation, the Telemac environment can be loaded as follows:

cd ROOT/telemac-mascaret/configs/
source pysource.mint22.sh

The installer scripts will clone the telemac-mascaret GitLab repo (with the assigned tag), and a salome folder, in which it unpacks the SALOME tarball. If you encounter errors with SALOME, check out the detailed SALOME installation instructions in the section on the “manual” installation of Telemac.

Test SALOME

SALOME is installed in the ROOT/salome now, and you can run the GUI as follows:

cd ROOT/salome
./salome

To test the installation, run the config.py script (after source-ing of the Telemac environment):

config.py

Installation example#

Assume you are working on Debian 12, accordingly you downloaded SALOME-9.15.0-native-DB12-SRC.tar.gz, defined the ROOT directory as /home/HyInfo/opt/, and downloaded telemac_debian12_installer.sh. Thus, the installation can be started with these commands:

cd /home/HyInfo/opt
chmod +x telemac_debian12_installer.sh
./telemac_debian12_installer.sh --root "/home/HyInfo/opt" --salome-tar "/home/HyInfo/opt/SALOME-9.15.0-native-DB12-SRC.tar.gz"

Now, you can activate the Telemac environment as follows:

cd /home/HyInfo/opt/telemac-mascaret/configs/
source pysource.debian12.sh

Installation example with another version#

Assume you are working on Debian 12, accordingly you downloaded SALOME-9.15.0-native-DB12-SRC.tar.gz, defined the ROOT directory as /home/HyInfo/opt/, downloaded telemac_debian12_installer.sh, and want to install Telemac v9.5.0 (if that existed at https://gitlab.pam-retd.fr/otm/telemac-mascaret.git). This installation can be started with these commands:

cd /home/HyInfo/opt
chmod +x telemac_debian12_installer.sh
./telemac_debian12_installer.sh --root "/home/HyInfo/opt" --tag="v9.5.0" --salome-tar "/home/HyInfo/opt/SALOME-9.15.0-native-DB12-SRC.tar.gz"

Now, you can activate the Telemac environment as follows:

cd /home/HyInfo/opt/telemac-mascaret/configs/
source pysource.debian12.sh

Test TELEMAC#

Estimated duration: 5-10 minutes.

Load the TELEMAC environment:

cd ROOT/telemac-mascaret/configs/
source pysource.debian12.sh

cd ROOT/telemac-mascaret/configs/
source pysource.mint22.sh

Run a predefined case from the examples folder:

cd ~/opt/telemac-mascaret/examples/telemac2d/gouttedo
telemac2d.py t2d_gouttedo.cas

Examples not working?

Do not panic. If config.py succeeded and the build ended with “My work is done”, your installation is usually fine. Most example failures come from environment issues or missing large files. Ensure you have sourced the correct pysource.*.sh, installed all Git requirements including Git LFS, checked out the right version, and pulled the full repository. If needed, re-clone with Git LFS enabled and recompile TELEMAC, starting from the git section.

To verify parallelism, install htop to visualize CPU usage:

sudo apt update
sudo apt install htop

Start the CPU monitor:

htop

In a new terminal tab, run a TELEMAC example with the --ncsize=N flag, where N is the number of logical CPUs to use (ensure at least N are available):

cd ~/opt/telemac-mascaret/examples/telemac2d/gouttedo
telemac2d.py t2d_gouttedo.cas --ncsize=4

Alternatively, use --nctile and --ncnode to specify cores per node (NCTILE) and number of nodes (NCNODE), respectively, with NCSIZE = NCTILE * NCNODE. The following two commands are equivalent (from ~/opt/telemac-mascaret/examples/telemac2d/donau):

telemac2d.py t2d_donau.cas --nctile=4 --ncnode=2
telemac2d.py t2d_donau.cas --ncsize=8

Got errors?

If there are severe errors, the automatic installer might not have worked for your system (or subversion). In this case, it is safest, to start over and install Telemac manually.

Generate TELEMAC Documentation#

TELEMAC includes many application examples under /telemac-mascaret/examples/, and you can build the user and reference manuals locally. First, load the TELEMAC environment:

source ~/opt/telemac-mascaret/configs/pysource.mint22.sh

To generate the user manual (this can take a while and requires latex, that is, texlive on Debian/Ubuntu):

doc_telemac.py

To generate the reference manual:

doc_telemac.py --reference

To create documentation and validation reports for all example cases:

validate_telemac.py

Note

validate_telemac.py iterates through many examples. Some may fail if optional modules are not installed (e.g., HERMES) or if an example is outdated. Building PDFs typically requires a LaTeX toolchain (for example, texlive on Debian/Ubuntu); install it if the documentation step reports missing LaTeX executables.

Utilities (Pre- & Post-processing)#

To install pre- and post-processing utilities, refer to the instructions in the manual installation section, such as BlueKenue or the Q4TS plugin in QGIS. Note that for the Q4TS plugin, your SALOME executable path is /ROOT/salome/salome, and your Telemac environnement script is /ROOT/telemac-mascaret/configs/pysource.debian12.sh (or /ROOT/telemac-mascaret/configs/pysource.mint22.sh if you installed on Ubuntu/Mint).
