Implementation of a XFEM toolbox in Diffpack [PDF]
International Conference on Extended Finite Element Methods - XFEM 2013, September 11 – 13, 2013, Ly, 2013 The Diffpack Development Framework is an object-oriented software environment for the numerical solution of partial differential equations (PDEs). By its design, Diffpack intends to close the gap between black-box simulation packages and technical computing environments using interpreted computer languages.
