Detailed Description

Vector coefficient defined by a vector GridFunction.

Definition at line 823 of file coefficient.hpp.

Constructor & Destructor Documentation

VectorGridFunctionCoefficient() [1/2]

mfem::VectorGridFunctionCoefficient::VectorGridFunctionCoefficient ( )

inline

Construct an empty coefficient. Calling Eval() before the grid function is set will cause a segfault.

Definition at line 831 of file coefficient.hpp.

VectorGridFunctionCoefficient() [2/2]

mfem::VectorGridFunctionCoefficient::VectorGridFunctionCoefficient

(

const GridFunction *

gf

)

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

Member Function Documentation

Eval() [1/2]

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

overridevirtual

Evaluate the vector coefficients at all of the locations in the integration rule and write the vectors into the columns of matrix M.

Reimplemented from mfem::VectorCoefficient.

Definition at line 461 of file coefficient.cpp.

Eval() [2/2]

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

overridevirtual

Evaluate the vector coefficient at ip.

Implements mfem::VectorCoefficient.

Definition at line 445 of file coefficient.cpp.

GetGridFunction()

const GridFunction * mfem::VectorGridFunctionCoefficient::GetGridFunction ( ) const

inline

Returns a pointer to the grid function in this Coefficient.

Definition at line 842 of file coefficient.hpp.

Project()

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

overridevirtual

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

This function uses the efficient QuadratureFunction::ProjectGridFunction to fill the QuadratureFunction.

Reimplemented from mfem::VectorCoefficient.

Definition at line 474 of file coefficient.cpp.

SetGridFunction()

void mfem::VectorGridFunctionCoefficient::SetGridFunction

(

const GridFunction *

gf

)

Set the grid function for this coefficient. Also sets the Vector dimension to match that of the gf.
