About XLiFE++#

History#

Initiated in 2012, XLiFE++ is the heir of 2 main finite element library at least partially developed in POEMS laboratory:

  • Melina (and its C++ avatar Melina++ and its former library Lena), developed mainly by Daniel Martin from IRMAR and Olivier de Bayser from SMP (POEMS ancestor) since 1990. The main goal was to use finite elements methods to solve easily various problems.

  • Melina++, the C++ avatar of Melina, developed since 2004 by Daniel Martin from IRMAR and Éric Lunéville from POEMS. The main goal was to use the abilities of C++ to improve Melina and raise some of its limitations due to the FORTRAN 77 language, but also to develop boundary elements methods.

  • Montjoie, developed since 2003 by Marc Duruflé, former PhD student of POEMS. The main goal was to offer fast resolution for some high order finite elements problems.

XLiFE++ is a C++ high level library devoted to finite elements methods in a broader sense. The main goal is to extend application fields by offering spectral methods, Discontinuous Galerkin methods, enriched finite elements, …

Credits#

The XLiFE++ library has been mainly developed by É. Lunéville and N. Kielbasiewicz of POEMS lab (UMR 7231, CNRS-ENSTA Paris-Inria). Some parts are inherited from Melina++ library developed by D. Martin (IRMAR lab, Rennes University, now retired) and É. Lunéville.
