Definition at line 70 of file gridfunc.hpp.

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

Construct a GridFunction using previously allocated array data.

The GridFunction 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 79 of file gridfunc.hpp.

mfem::GridFunction::GridFunction ( Mesh m,
std::istream &  input 
)

Construct a GridFunction on the given Mesh, using the data from input.

The content of input should be in the format created by the method Save(). The reconstructed FiniteElementSpace and FiniteElementCollection are owned by the GridFunction.
