XLiFE++ - eXtended Library of Finite Elements in C++

XLiFE++ is an FEM-BEM C++ code developed by P.O.e.m.s. laboratory and I.R.M.A.R. laboratory, that can solve 1D / 2D / 3D, scalar / vector, transient / stationnary / harmonic problems. It provides:

• Advanced mesh tools, with refinement methods, including an advanced interface to the mesh generator Gmsh
• High order Lagrange Finite Elements (every order)
• High order edge Finite Elements (every order)
• Boundary Elements methods: Laplace, Helmholtz, Maxwell, Stokes (in progress)
• Essential conditions (periodic, quasi-periodic)
• Absorbing conditions: DtN, PML, ...
• Export to visualization tools such as Gmsh, Paraview, Matlab
• Many solvers (direct solvers, iterative solvers, eigenvalue solvers, wrappers to Arpack, UmfPack and Eigen libraries)

From 2011 to 2014, its development has been supported by the SIMPOSIUM European Project .

From 2015 to 2018, its development has been supported by the DGA/MRIS .
