void mfem::CoarseFineTransformations::MakeCoarseToFineTable ( Table coarse_to_fine,
bool  want_ghosts = false 
) const

Invert the 'embeddings' array: create a Table with coarse elements as rows and fine elements as columns. If 'want_ghosts' is false, parallel ghost fine elements are not included in the table.

Array<Embedding> mfem::CoarseFineTransformations::embeddings

Fine element positions in their parents.

DenseTensor mfem::CoarseFineTransformations::point_matrices[Geometry::NumGeom]

A "dictionary" of matrices for IsoparametricTransformation. Use Embedding::{geom,matrix} to access a fine element point matrix.
