◆ CurlGridFunctionCoefficient()

mfem::CurlGridFunctionCoefficient::CurlGridFunctionCoefficient ( const GridFunction * gf)

Construct the coefficient with a vector grid function gf. The grid function is not owned by the coefficient.

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]

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

Evaluate the vector curl coefficient at ip.

Implements mfem::VectorCoefficient.

Definition at line 534 of file coefficient.cpp.

◆ GetGridFunction()

const GridFunction * mfem::CurlGridFunctionCoefficient::GetGridFunction ( ) const
inline

Get the vector grid function.

Definition at line 904 of file coefficient.hpp.

◆ SetGridFunction()

void mfem::CurlGridFunctionCoefficient::SetGridFunction ( const GridFunction * gf)

Set the vector grid function.
