It is a C++ high level library devoted to extended finite elements methods. Writing programs using \xlifepp needs only basic knowledge of C++ language, so that it can be used to teach finite elements methods, but it is quite perfect for research. 18 19\medskip 20 21\xlifepp is self-consistent. It provides advanced mesh tools, with refinement methods, has every kind of elements (including pyramids) needed by finite elements methods, boundary elements methods or discontinuous galerkin methods, direct/iterative solvers and eigen solvers. Next to this, it provides also a wide range of interfaces to well-known libraries or softwares, such that \umfpack, \arpackpp, and an advanced interface to the mesh generator \gmsh, so that you can do everything needed in a single program. 22 23\medskip 24 25 26This documentation is dedicated to students at Master level, to engineers and researchers at any level, in so far as partial differential equations are concerned. 27
