Detailed Description

Vector coefficient defined as a product of scalar and vector coefficients.

Definition at line 1847 of file coefficient.hpp.

Constructor & Destructor Documentation

ScalarVectorProductCoefficient() [1/2]

mfem::ScalarVectorProductCoefficient::ScalarVectorProductCoefficient	(	double	A,
		VectorCoefficient &	B
	)

Constructor with constant and vector coefficient. Result is A * B.

Definition at line 1105 of file coefficient.cpp.

ScalarVectorProductCoefficient() [2/2]

mfem::ScalarVectorProductCoefficient::ScalarVectorProductCoefficient	(	Coefficient &	A,
		VectorCoefficient &	B
	)

Constructor with two coefficients. Result is A * B.

Definition at line 1111 of file coefficient.cpp.

Member Function Documentation

Eval() [1/3]

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

virtual

Evaluate the coefficient at ip.

Implements mfem::VectorCoefficient.

Definition at line 1124 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.
