Eval()

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

overridevirtual

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.

GetQuadFunction()

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

inline

Definition at line 2390 of file coefficient.hpp.

Project()

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

overridevirtual

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

Reimplemented from mfem::Coefficient.
