Extended Finite Element Method
The extended finite element method (XFEM), also known as generalized finite element method (GFEM) or partition of unity method (PUM) is a numerical technique that extends the classical finite element method (FEM) approach by enriching the solution space for solutions to differential equations with discontinuous functions.
