Detailed Description

Vector with associated FE space and LinearFormIntegrators.

Definition at line 23 of file linearform.hpp.

Constructor & Destructor Documentation

mfem::LinearForm::LinearForm ( FiniteElementSpace f)
inline

Creates linear form associated with FE space *f.

The pointer f is not owned by the newly constructed object.

Definition at line 77 of file linearform.hpp.

mfem::LinearForm::LinearForm ( FiniteElementSpace f,
LinearForm lf 
)

Create a LinearForm on the FiniteElementSpace f, using the same integrators as the LinearForm lf.

The pointer f is not owned by the newly constructed object.

The integrators in lf are copied as pointers and they are not owned by the newly constructed LinearForm.

Definition at line 19 of file linearform.cpp.

mfem::LinearForm::LinearForm ( )
inline

Create an empty LinearForm without an associated FiniteElementSpace.

The associated FiniteElementSpace can be set later using one of the methods: Update(FiniteElementSpace *) or Update(FiniteElementSpace *, Vector &, int).

Definition at line 93 of file linearform.hpp.

mfem::LinearForm::LinearForm ( FiniteElementSpace f,
double *  data 
)
inline

Construct a LinearForm using previously allocated array data.

The LinearForm does not assume ownership of data which is assumed to be of size at least f->GetVSize(). Similar to the Vector constructor for externally allocated array, the pointer data can be NULL. The data array can be replaced later using the method SetData().

Definition at line 100 of file linearform.hpp.

mfem::LinearForm::~LinearForm ( )

Destroys linear form.

Definition at line 336 of file linearform.cpp.

Reimplemented in mfem::ParLinearForm.

Definition at line 277 of file linearform.cpp.

double mfem::LinearForm::operator() ( const GridFunction gf) const

Return the action of the LinearForm as a linear mapping.

Linear forms are linear functionals which map GridFunctions to the real numbers. This method performs this mapping which in this case is equivalent as an inner product of the LinearForm and GridFunction.
