Public Member Functions

 TransferMap (const GridFunction &src, const GridFunction &dst)
 Construct a new TransferMap object which transfers degrees of freedom from the source GridFunction to the destination GridFunction.
 
void Transfer (const GridFunction &src, GridFunction &dst) const
 Transfer the source GridFunction to the destination GridFunction.
 

Detailed Description

TransferMap represents a mapping of degrees of freedom from a source GridFunction to a destination GridFunction.

This map can be constructed from a parent Mesh to a SubMesh or vice versa. Additionally one can create it between two SubMeshes that share the same root parent. In this case, a supplemental FiniteElementSpace is created on the root parent Mesh to transfer degrees of freedom.
