Abstract
ngsxfem is an add-on library to Netgen/NGSolve, a general purpose, high performance finite element library for the numerical solution of partial differential equations. The add-on enables the use of geometrically unfitted finite element technologies known under different labels, e.g. XFEM, CutFEM, TraceFEM, Finite Cell, fictitious domain method or Cut-Cell methods, etc.. Both, Netgen/NGSolve and ngsxfem are written in C++ with a rich Python interface through which it is typically used. ngsxfem is an academic software. Its primary intention is to facilitate the development and validation of new numerical methods.
