Detailed Description

a class that computes and stores positions and jacobians at each quadrature point

Note

analogous to mfem::GeometricFactors, except that it implements the position/jacobian calculations on boundary elements and on simplex elements

Constructor & Destructor Documentation

GeometricFactors() [1/2]

serac::GeometricFactors::GeometricFactors	(	const Domain &	domain,
		int	q,
		mfem::Geometry::Type	elem_geom
	)

calculate positions and jacobians for quadrature points belonging to elements with the specified geometry, belonging to the provided mesh.

Parameters

domain	the domain of integration
q	a parameter controlling the number of quadrature points per element
elem_geom	which kind of element geometry to select

Definition at line 62 of file geometric_factors.cpp.

GeometricFactors() [2/2]

serac::GeometricFactors::GeometricFactors	(	const Domain &	domain,
		int	q,
		mfem::Geometry::Type	elem_geom,
		FaceType	type
	)

calculate positions and jacobians for quadrature points belonging to boundary elements with the specified geometry, belonging to the provided mesh.

Parameters

domain	the domain of integration
q	a parameter controlling the number of quadrature points per element
elem_geom	which kind of element geometry to select
type	whether or not the faces are on the boundary (supported) or interior (unsupported)

Member Data Documentation

J

mfem::Vector serac::GeometricFactors::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 NE) where

• NQ = number of quadrature points per element,
• SDIM = space dimension of the mesh = mesh.SpaceDimension(),
• DIM = dimension of the mesh = mesh.Dimension(), and
• NE = number of elements in the mesh.

Definition at line 58 of file geometric_factors.hpp.

X

mfem::Vector serac::GeometricFactors::X

Mapped (physical) coordinates of all quadrature points.

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

• NQ = number of quadrature points per element,
• SDIM = space dimension of the mesh = mesh.SpaceDimension(), and
• NE = number of elements in the mesh.
