Salome2Py 0.4.0

Convert Salomé-Meca MED meshes and Code_Aster .comm files into NumPy-ready Python data.

Salome2Py

CLI that converts a Salomé-Meca MED mesh plus its matching Code_Aster .comm file into NumPy-friendly Python arrays (node, elem, mater, pdof, nodf, etc.).

Installation (pipx)

pipx keeps console tools isolated per-virtualenv and works the same on Linux, macOS, and Windows.

1. Install pipx

   • Linux/macOS:

     python3 -m pip install --user pipx
     python3 -m pipx ensurepath
     

   • Windows (PowerShell):

     py -m pip install --user pipx
     py -m pipx ensurepath
     

   Reload the shell so the pipx path is active.

2. Install Salome2Py

   • From PyPI (once published):

     pipx install Salome2Py
     

   • From a local clone:

     pipx install .
     

This exposes the Salome2Py command globally without polluting your base interpreter. (You can still run python main.py ... directly if you prefer.)

Usage

Salome2Py [-m] [-b] [-o output.py] path/to/case.med path/to/case.comm

• -m, --mater — include the material matrix parsed from DEFI_MATERIAU (AFFE_MATERIAU must map groups to materials).
• -b, --boundary — include prescribed DOFs (pdof) and nodal loads (nodf) derived from DDL_IMPO / FORCE_FACE.
• -o, --output — optional destination file (defaults to <case_folder>.py).

By default, the generated Python file is written to the directory where you invoke the command (e.g., running inside /tmp creates /tmp/input.py for an Input/ case). Use -o to override the path.

Without -m or -b, the generator writes only node, elem, eltp, and bc_method, skipping the more expensive parsing steps automatically.

Development

Install deps once (if you are not using the packaged CLI):

python -m pip install --break-system-packages meshio h5py

Then run the tool directly:

python main.py -m -b Input/DoubleCubeCase.med Input/DoubleCubeCase.comm
