computed_factors

int mfem::FaceGeometricFactors::computed_factors

Definition at line 2995 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 3030 of file mesh.hpp.

IntRule

const IntegrationRule* mfem::FaceGeometricFactors::IntRule

Definition at line 2994 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-1) 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,
