	The implementation of the FEM scheme on this element type. Calculates all the values that you get solving the integrals of the FEM with the shape functions of a 1D linear element and writes them to the corresponding spots in the global capacitance matrix, stiffness matrix and forcing vector.

	The implementation of a boundary cell in the FEM scheme on this element type. If this cell is a boundary cell, only this function will be run.

	Sets up a reference_wrapper vector to the elements within the matrix object. This adds a bit of pre-calculation overhead, but always allows const time element access even for matrix object that don't normally have const time random access. This of course assumes a static grid.

	Constructor for a GenericElement object. Sets all parameters that are known at creation.

Detailed Description

template<typename T>
class OneDimLinearElement< T >

Concrete Implementation of a 1D linear (line) element for the FEM.

Constructor & Destructor Documentation

OneDimLinearElement()

template<typename T >

OneDimLinearElement< T >::OneDimLinearElement	(	bool	is_boundary_point,
		std::map< std::string_view, std::vector< int > >	all_boundary_points,
		std::vector< int >	nodal_values,
		SimulationClassBase< T > *	sim,
		int	cell_nr,
		ElementProperties< T >	props
	)

Constructor for a OneDimLinearElement object.

Parameters

is_boundary_point	Flag whether this element has boundary nodes or not.
all_boundary_points	A map containg the types of boundary conditions and all the nodes belonging to that type (to allow for multiple boundary conditions in one element).
nodal_values	The node numbers of all nodes within the element. Needed to sort them into the correct position within the matrix.
sim	The pointer to the sim class.
cell_nr	The number of the cell.
props	Properties of the element (length and area).
