Member Function Documentation

◆ Eval() [1/3]

virtual void mfem::VectorCoefficient::Eval

Evaluate the vector coefficient in the element described by T at the point ip, storing the result in V.

Note: When this method is called, the caller must make sure that the IntegrationPoint associated with T is the same as ip. This can be achieved by calling T.SetIntPoint(&ip).

◆ Eval() [2/3]

void mfem::VectorCoefficient::Eval

Evaluate the vector coefficient in the element described by T at all points of ir, storing the result in M.

The dimensions of M are GetVDim() by ir.GetNPoints() and they must be set by the implementation of this method.

The general implementation provided by the base class (using the Eval method for one IntegrationPoint at a time) can be overloaded for more efficient implementation.

Note: The IntegrationPoint associated with T is not used, and this method will generally modify this IntegrationPoint associated with T.

Definition at line 265 of file coefficient.cpp.

◆ Eval() [3/3]

void mfem::VectorQuadratureFunctionCoefficient::Eval	(	Vector &	V,
		ElementTransformation &	T,
		const IntegrationPoint &	ip
	)

virtual

Evaluate the vector coefficient in the element described by T at the point ip, storing the result in V.

Note: When this method is called, the caller must make sure that the IntegrationPoint associated with T is the same as ip. This can be achieved by calling T.SetIntPoint(&ip).

Implements mfem::VectorCoefficient.

Definition at line 1588 of file coefficient.cpp.

◆ GetQuadFunction()

const QuadratureFunction& mfem::VectorQuadratureFunctionCoefficient::GetQuadFunction ( ) const

inline

Definition at line 2255 of file coefficient.hpp.

◆ Project()

void mfem::VectorQuadratureFunctionCoefficient::Project ( QuadratureFunction & qf )

virtual

Fill the QuadratureFunction qf by evaluating the coefficient at the quadrature points.

The vdim of the VectorCoefficient should be equal to the vdim of the QuadratureFunction.

Reimplemented from mfem::VectorCoefficient.

Definition at line 1615 of file coefficient.cpp.

◆ SetComponent()

void mfem::VectorQuadratureFunctionCoefficient::SetComponent	(	int	index_,
		int	length_
	)

Set the starting index within the QuadFunc that'll be used to project outwards as well as the corresponding length. The projected length should have the bounds of 1 <= length <= (length QuadFunc - index).
