GridFunction

class GridFunction : public Vector

Class for grid function - Vector with asociated FE space.

Public Methods
GridFunction(FiniteElementSpace * f): Creates grid function associated with *f.
void GetNodalValues(int i, Array<double> &nval, int vdim = 1) const: Returns the values in the vertices of i'th element for dimension vdim.
void GetNodalValues(Vector &nval, int vdim = 1) const: Return the values as a vector on mesh vertices for dimension vdim.
inline void PrintMesh(ostream & out = cout) const: Prints the mesh associated with the given FE space.
inline void PrintFES(ostream & out = cout) const: Prints the FE space on which grid function lives.
inline void PrintData(ostream & out = cout): Prints the entries of the Vector in dofs of FE space.
inline void Print(ostream & outMesh = cout, ostream & outFES = cout, ostream & out = cout): Prints the mesh, FE space and entries of the Vector in dofs.
GridFunction& operator= (double value): Redefine '=' for GridFunction = constant.
~GridFunction(): Destroys grid function.
