Finite element discretization library

Interface for mortar element assembly. The MortarIntegrator interface is used for performing Petrov-Galerkin finite element assembly on intersections between elements. The quadrature rules are to be generated by a cut algorithm (e.g., mfem::Cut). The quadrature rules are defined in the respective trial and test reference frames. Trial and test spaces can be associated with different element shapes (e.g., triangles and quadrilaterals) and different polynomial orders (e.g., 1 and 4). This class is designed to work in conjunction with the MFEM/moonolith module but it can be used also for other applications. More...
