MEF++ is a computer simulation software implementing the finite-element method, written in C++ and developped at Université Laval by the Groupe Interdisciplinaire de Recherche en Éléments Finis (GIREF).[1]. MEF++ is a general[2] software tool that enables the resolution of various problems [3], one of its special features being the resolution of very large size multi-physics problems[4]. MEF++ uses the PETSc library for solving linear systems and the interface provided by the MPI norm for parallel computing.


In 1995, the GIREF was composed of researchers from various fields (civil, mechanical and chemical engineers and also mathematicians) willing to have a common finite element modeling tool that will suite their common needs.[5][6] A developper teams was put together in 1996[7] to answer these needs. Working to code the algorithms and numerical methodologies developed within the GIREF reserach activities. Since 2007[8], theses efforts are financially sustained by the Natural Sciences and Engineering Research Council of Canada (NSERC) and industrial partners: Michelin since 2006, followed by Hydro-Québec and Bodycad since 2017.


MEF++ is a general finite elements software completely parallelized [9] [4] which use PETSc (providing iterative methods, but also direct solvers as MUMPS, SuperLU, MKL PARDISO), PARMETIS [10] or PTSCOTCH, TAO [11] and the MPI norm. MEF++ is offering functionalities[7] for anisotropic mesh adaptation [12] [13] , solving steady or unsteady 1D-2D-3D problems, deformable-deformable friction contact problems, fluid structure interaction, shape optimization, large deformations[14] and mechanical damage computations[15] [16]

Being a shared development effort involving academic and industrial partners, and thus aiming for a well verified stability and numerical reproducibility other time, developments inside MEF++ framework are integrated thanks to a version control solution and a software quality insurance process. Part of this process is the release and test of nightly builds on more than 15 different environments with more than 2700 non-regression tests. Sample of these nightly builds are publicly accessible.[17]
