◆ SetDomain()

virtual void Element::SetDomain ( std::map< unsigned int, std::shared_ptr< Node > > & nodes )

pure virtual

Sets the finite element dependance among objects.

Parameters

nodes The Node list of the Mesh object.

Note: This function sets the relation between Node and Element objects.
