Detailed Description

Vector coefficient defined by a vector GridFunction.

Definition at line 683 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 691 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.

Definition at line 383 of file coefficient.cpp.

Member Function Documentation

◆ Eval() [1/2]

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

Evaluate the vector coefficient at ip.

Implements mfem::VectorCoefficient.

Definition at line 395 of file coefficient.cpp.

◆ Eval() [2/2]

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

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 411 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 702 of file coefficient.hpp.

◆ Project()

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

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 424 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.

Definition at line 390 of file coefficient.cpp.
