SALOME is an open-source software that provides a generic platform for Pre- and Post-Processing for numerical simulation.

The EPXDATA module is dedicated to the interactive design of EPX datasets, using menus and dialog boxes built from the syntax of the EPX directives in the User's Manual. The data are affected to the mesh data provided by the SMESH module of the SALOME platform.

The EPXDATA module is compatible with the SALOME-MECA platform, derived from the generic SALOME platform and dedicated to numerical simulation in mechanics. SALOME-MECA provides an execution module for EPX (basically named EPX), complementary to the EPXDATA module and designed to manage studies based on existing datasets, built within SALOME or not.

EPX is compatible with the MEDFile format for meshes and results.

For EPX versions > 2014.0, all executables are statically linked with the MED library (and HDF5 library).

EPX Version MEDfile library HDF5 library
2016.0 3.0.7 1.8.10


For EPX 2013 version, the correct executable must be installed and the MED library ( > v3.0.0) must be available on the system.

The MEDFile v3 library can be obtained from the SALOME et SALOME-MECA platforms or individually using the following download link (requires the prior installation of the HDF5 library).

The main EPX parallel framework is based on automatic domain decomposition and MPI communications between subdomains (one subdomain per MPI process).

The provided EPX // executables are designed to work with OpenMPI under Linux and MacOS X, and Intel MPI under Windows (see the here for more details about the available implementations).

An experimental support of the KAAPI library (INRIA/LIG) for SMP calculations is also provided, although still under strong development. Both parallel frameworks can be mixed into a hybrid parallel strategy, currently under development to address massively parallel supercomputers (see REPDYN Project website).

EPX logo is available for download in both vectorial and raw/png formats (color and monochrome).
