Member Function Documentation

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.

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

Definition at line 2147 of file coefficient.hpp.

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

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

Reimplemented from mfem::Coefficient.
