SOLVERLAB GUI not available

Luc · December 20, 2025, 9:40pm

Hello,

I would like to be able to launch SOLVERLAB in GUI mode directly from SALOME gui interface. But I can’t find a way, icon is not present.

System is fresh install of Ubuntu 24.04, with SALOME version is 9.15.0-native tarball. Salome is launched from the terminal, the gui opened well, no error in the terminal, I even could follow a tuto on building a part with the shaper module and succeed with computing a mesh on it.

I tried to recompile salome from source code (in ARCHIVE folder) with sat instructions, I got success messages, including for the SOLVERLAB line, but I still can’t find the module on salomé window.

I tried to follow instructions from GitHub - ndjinga/SOLVERLAB: PDE solver lab using SALOME/MEDCoupling meshes and PETSc matrices but it seems that variable $SOLVERLABGUI doesn’t exist (it’s empty). Sourcing the env_launch.sh on root directory doesn’t help.

What am I missing ?

SOLVERLABGUI interface is deprecated and is not maintained anymore. You should instead use the PYTHON API. See examples here:

# 
# # SolverLab documentation for Salome
# 
# ## Introduction
# 
# **SOLVERLAB** is divided into two Python packages:
# 
# - `cdmath` gathers elementary tools to build and solve matrix systems
# - `CoreFlows` gathers tools for efficiently solving classical engineering problems
# 
# **SOLVERLAB** brings together the `MEDCOUPLING` and `PETSc` libraries to create a powerful, practical and easy-to-use tool for solving partial differential equations.
# 
# The project is initially hosted on [GitHub](https://github.com/ndjinga/SOLVERLAB) and a stable version is incorporated into **Salome**.
# 
# ## Installation
# 
# **SOLVERLAB** is installed with **Salome**. A set of resources is available in the installation: `path-to-salome/INSTALL/SOLVERLAB/share`, in particular the documentation for the `CoreFlows` module in pdf in `SOLVERLAB/share/doc` or in `doxygen` form gathering all the options available for each model can be found in `SOLVERLAB/share/doc/coreflows-dev-doc/html/index.html`.
