Member Function Documentation

◆ Eval()

double mfem::QuadratureFunctionCoefficient::Eval	(	ElementTransformation &	T,
		const IntegrationPoint &	ip
	)

virtual

Evaluate the coefficient in the element described by T at the point ip.

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::Coefficient.

Definition at line 1573 of file coefficient.cpp.

◆ GetQuadFunction()

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

inline

Definition at line 2144 of file coefficient.hpp.

◆ Project()

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

virtual

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

Reimplemented from mfem::Coefficient.
