| Cut | All subclasses of Cut will implement intersection routines and quadrature point generation within the cut in the intersection of two elements. Although, this class is designed to support MortarAssembler and ParMortarAssembler, it can be used for any problem requiring to perform Petrov-Galerkin formulations on non-matching elements |
| MortarAssembler | This class implements the serial variational transfer between finite element spaces. Variational transfer has been shown to have better approximation properties than standard interpolation. This facilities can be used for supporting applications which require the handling of non matching meshes. For instance: General multi-physics problems, fluid structure interaction, or even visualization of average quantities within subvolumes This algorithm allows to perform quadrature in the intersection of elements of two separate and unrelated meshes. It generates quadrature rules in the intersection which allows us to integrate-with to machine precision using the mfem::MortarIntegrator interface. See https://doi.org/10.1137/15M1008361 for and in-depth explanation. At this time curved elements are not supported |
| MortarIntegrator | 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 |

| VectorL2MortarIntegrator | Integrator for vector finite elements. Experimental. \( (u, v)_{L^2(\mathcal{T}_m \cap \mathcal{T}_s)}, u \in U(\mathcal{T}_m ) and v \in V(\mathcal{T}_s ) \) |
| ParMortarAssembler | This class implements the parallel variational transfer between finite element spaces. Variational transfer has been shown to have better approximation properties than standard interpolation. This facilities can be used for supporting applications which require the handling of non matching meshes. For instance: General multi-physics problems, fluid structure interaction, or even visualization of average quantities within subvolumes. This particular code is also used with LLNL for large scale multilevel Monte Carlo simulations. This algorithm allows to perform quadrature in the intersection of elements of two separate, unrelated, and arbitrarily distributed meshes. It generates quadrature rules in the intersection which allows us to integrate with to machine precision using the mfem::MortarIntegrator interface. See https://doi.org/10.1137/15M1008361 for and in-depth explanation. At this time curved elements are not supported. Convex non-affine elements are partially supported, however, high order (>3) finite element discretizations or nonlinear geometric transformations might generate undesired oscillations. Discontinuous fields in general can only be mapped to order 0 destination fields. For such cases localized versions of the projection will have to be developed |
