Constructor & Destructor Documentation

◆ ShapeMatrices() [1/2]

template<class T_N , class T_DNDR , class T_J , class T_DNDX >

NumLib::ShapeMatrices< T_N, T_DNDR, T_J, T_DNDX >::ShapeMatrices ( )

delete

Not default constructible, dimensions always must be given.

The default constructor has been deleted explicitly, because with dynamically allocated matrices it is rather easy to forget the required resize() call. Note: the resize() member is also deleted now.

◆ ShapeMatrices() [2/2]

template<class T_N , class T_DNDR , class T_J , class T_DNDX >

NumLib::ShapeMatrices< T_N, T_DNDR, T_J, T_DNDX >::ShapeMatrices	(	std::size_t	local_dim,
		std::size_t	global_dim,
		std::size_t	n_nodes )

inline

Initialize matrices and vectors

Parameters

local_dim	Spatial dimension of the element e.g. 1 for line, 2 for quad, and 3 hex etc.
global_dim	Spatial dimension of the element's exterior space e.g. 3 for a quad representing a boundary of a hex element.
n_nodes	The number of element nodes

Definition at line 79 of file ShapeMatrices.h.
