This graph shows which files directly or indirectly include this file:

Classes
struct	serif::discretization::backend::mfem::TensorWorkspace
	A workspace for tensor contractions to avoid repeated allocations and pack memory (TODO: does this actual pack memory in a useful manner when using mfem vectors? Probably something to look into). More...
class	serif::discretization::backend::mfem::TensorBasis
	A class that represents a tensor basis for a finite element. This class is used to evaluate the basis functions and their derivatives at a set of reference points. More...
struct	serif::discretization::backend::mfem::TensorBasis::Product
	A struct that represents a product of one-dimensional basis functions. More...
class	serif::discretization::backend::mfem::TensorBasisCache
	Share immutable tensor plans within one operator; copied rules are keyed by their contents. More...
struct	serif::discretization::backend::mfem::TensorBasisCache::Entry
	A struct that represents an entry in the TensorBasisCache. Each entry contains a non-owning pointer to a finite element, the reference operation, the number of copies, the points used to construct the TensorBasis, and a shared pointer to the TensorBasis itself. More...
