Detailed Description

The MFEMQuadratureContext struct is used to describe the context in which we are trying to resolve an MFEM integration rule. This includes the geometry type, the order of the geometry weight, any dynamic orders, the domain or set of domains, and the mapping kind.

The idea here is that there is some information we can know at compile time (e.g. the role the particular integration is playing) and some we can only know at runtime (e.g. a manual quadrature boost requested by the user) so QuadratureContext contains all of that information which can then be turned into a single quadrature order. This is born out of the recognition that there is really not one good choice for quadrature order; rather, different systems have different accuracy requirements and should generally use the lowest order that is sufficient for their needs.

Member Data Documentation

◆ domain

domain::DomainOrSet serif::discretization::quadrature::backend::mfem::MFEMQuadratureContext::domain = domain::AllDomains{}

The domain or set of domains for which we are trying to resolve an MFEM integration rule.

◆ dynamic_orders

std::span<const int> serif::discretization::quadrature::backend::mfem::MFEMQuadratureContext::dynamic_orders {}

The geometry type of the element for which we are trying to resolve an MFEM integration rule.

◆ geometry_weight_order

int serif::discretization::quadrature::backend::mfem::MFEMQuadratureContext::geometry_weight_order = 0

The order of the geometry weight.

◆ mapping

MappingKind serif::discretization::quadrature::backend::mfem::MFEMQuadratureContext::mapping = MappingKind::none

The mapping kind of the quadrature rule.

◆ role

QuadratureRole serif::discretization::quadrature::backend::mfem::MFEMQuadratureContext::role = QuadratureRole::discretization
