Constructor & Destructor Documentation

◆ SubDOFHandlerMultiDim()

SubDOFHandlerMultiDim::SubDOFHandlerMultiDim ( std::shared_ptr< DOFHandlerMultiDim dh,
unsigned int  component_idx 
)

Creates a new dof handler for a component of FESystem.

The component_idx indicates the index of finite-element from dh for which the new sub- handler is made. The numbering of dofs in sub-handler is compatible with the original handler.
