computed_factors

int mfem::FaceGeometricFactors::computed_factors

Definition at line 2242 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 2277 of file mesh.hpp.

IntRule

const IntegrationRule* mfem::FaceGeometricFactors::IntRule

Definition at line 2241 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.

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.
