◆ computed_factors

int mfem::FaceGeometricFactors::computed_factors

Definition at line 2848 of file mesh.hpp.

◆ detJ

Vector mfem::FaceGeometricFactors::detJ

Determinants of the Jacobians at all quadrature points.

This array uses a column-major layout with dimensions (NQ x NF) where

NQ = number of quadrature points per face, and
NF = number of faces in the mesh.

Definition at line 2883 of file mesh.hpp.

◆ IntRule

const IntegrationRule* mfem::FaceGeometricFactors::IntRule

Definition at line 2847 of file mesh.hpp.

◆ J

Vector mfem::FaceGeometricFactors::J

Jacobians of the element transformations at all quadrature points.

This array uses a column-major layout with dimensions (NQ x SDIM x DIM x NF) where

NQ = number of quadrature points per face,
SDIM = space dimension of the mesh = mesh.SpaceDimension(),
DIM = dimension of the mesh = mesh.Dimension(), and
NF = number of faces in the mesh.

◆ mesh

const Mesh* mfem::FaceGeometricFactors::mesh

Definition at line 2846 of file mesh.hpp.

◆ normal

Vector mfem::FaceGeometricFactors::normal

Normals at all quadrature points.

This array uses a column-major layout with dimensions (NQ x DIM x NF) where

NQ = number of quadrature points per face,
SDIM = space dimension of the mesh = mesh.SpaceDimension(), and
NF = number of faces in the mesh.

◆ X

Vector mfem::FaceGeometricFactors::X

Mapped (physical) coordinates of all quadrature points.

This array uses a column-major layout with dimensions (NQ x SDIM x NF) where

NQ = number of quadrature points per face,
SDIM = space dimension of the mesh = mesh.SpaceDimension(), and
NF = number of faces in the mesh.
