inline

Definition at line 42 of file pgridfunc.hpp.

◆ ParGridFunction() [3/7]

mfem::ParGridFunction::ParGridFunction ( ParFiniteElementSpace pf,
double *  data 
)
inline

Construct a ParGridFunction using previously allocated array data.

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

Definition at line 51 of file pgridfunc.hpp.

◆ ParGridFunction() [4/7]

mfem::ParGridFunction::ParGridFunction ( ParFiniteElementSpace pf,
GridFunction gf 
)

Construct a ParGridFunction using a GridFunction as external data.

The parallel space *pf and the space used by *gf should match. The data from *gf is used as the local data of the ParGridFunction on each processor. The ParGridFunction does not assume ownership of the data.

Definition at line 24 of file pgridfunc.cpp.

◆ ParGridFunction() [5/7]

mfem::ParGridFunction::ParGridFunction ( ParFiniteElementSpace pf,
HypreParVector tv 
)

Creates grid function on (all) dofs from a given vector on the true dofs, i.e. P tv.

Definition at line 30 of file pgridfunc.cpp.

◆ ParGridFunction() [6/7]

mfem::ParGridFunction::ParGridFunction ( ParMesh pmesh,
const GridFunction gf,
const int *  partitioning = NULL 
)

Construct a local ParGridFunction from the given global GridFunction. If partitioning is NULL (default), the data from gf is NOT copied.

Definition at line 36 of file pgridfunc.cpp.

◆ ParGridFunction() [7/7]

mfem::ParGridFunction::ParGridFunction ( ParMesh pmesh,
std::istream &  input 
)

Construct a ParGridFunction on a given ParMesh, pmesh, reading from an std::istream.

In the process, a ParFiniteElementSpace and a FiniteElementCollection are constructed. The new ParGridFunction assumes ownership of both.
