aave: Maps which compute a common refinement (intersection) mesh and then integrate a piecewise-constant reconstruction. Conseravtive and monotone.
bilin: ESMF’s bilinear interpolation
mono: For spectral element (SE) grids, where the spectral element basis functions are replaced with a montone bases.
intbilin: Integrated bilinear. For finite element grids, the shape functions are replaced by a piecewise linear shape functions which are then integrated using a common refinement mesh
inttrilin: Integrated linear reconstruction using triangular grids?
highorder:
{algorithm}trn: For any map from grid a to grid b, one can compute an area weighted transpose map from grid b to grad a. In general, the tranpose map will not preserve the properties of the original map. However, the transpose of a conservative map will be conservative. The transpose of a monotone conservative map will be monotone and conservative.
