Member Function Documentation

◆ Eval() [1/2]

void mfem::VectorCoefficient::Eval	(	DenseMatrix &	M,
		ElementTransformation &	T,
		const IntegrationRule &	ir )

virtual

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.

Reimplemented from mfem::VectorCoefficient.

Definition at line 605 of file coefficient.cpp.

◆ Eval() [2/2]

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

inlinevirtual

Evaluate the vector coefficient at ip.

Implements mfem::VectorCoefficient.

Definition at line 631 of file coefficient.hpp.

◆ GetVec()

const Vector & mfem::VectorConstantCoefficient::GetVec ( ) const

inline

Return a reference to the constant vector in this class.
