Detailed Description

Vector coefficient defined as the linear combination of two vectors.

Definition at line 1631 of file coefficient.hpp.

Constructor & Destructor Documentation

◆ VectorSumCoefficient() [1/3]

mfem::VectorSumCoefficient::VectorSumCoefficient ( int dim )

Constructor with no coefficients. To be used with the various "Set" methods

Definition at line 994 of file coefficient.cpp.

◆ VectorSumCoefficient() [2/3]

mfem::VectorSumCoefficient::VectorSumCoefficient	(	VectorCoefficient &	A,
		VectorCoefficient &	B,
		double	alpha_ = `1.0`,
		double	beta_ = `1.0`
	)

Constructor with two vector coefficients. Result is alpha_ * A + beta_ * B

Definition at line 1004 of file coefficient.cpp.

◆ VectorSumCoefficient() [3/3]

mfem::VectorSumCoefficient::VectorSumCoefficient	(	VectorCoefficient &	A_,
		VectorCoefficient &	B_,
		Coefficient &	alpha_,
		Coefficient &	beta_
	)

Constructor with scalar coefficients. Result is alpha_ * A_ + beta_ * B_

Definition at line 1018 of file coefficient.cpp.

Member Function Documentation

◆ Eval() [1/3]

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

virtual

Evaluate the coefficient at ip.

Implements mfem::VectorCoefficient.

Definition at line 1044 of file coefficient.cpp.

◆ Eval() [2/3]

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() [3/3]

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.
