Detailed Description

Tri is a class containing the index references to nodes, its surface and its normal unit vector, it has a triangular shape and should not be degenerated, orientation must be defined in adequation with the mesh

Constructor & Destructor Documentation

◆ Tri()

Triangle::Tri::Tri	(	const std::vector< Nodes::Node > &	_p_node,
		const int	_NOD,
		const int	_idx,
		std::initializer_list< int >	_i
	)

inline

constructor used by readMesh Warning: mesh::indexReorder method call it with both _NOD = 0 and _p_node.size() > 0 TODO: get rid of _NOD and rewrite mesh::indexReorder

Parameters

[in]	_p_node	vector of nodes
[in]	_NOD	it is equal to _p_node.size() except if _NOD == 0
[in]	_idx	region index in region vector
[in]	_i	node index

inlinevirtual

returns Gauss points in result = vec_nod*Trianglea

Implements element< N, NPI >.

◆ integrales()

void Tri::integrales ( Triangle::prm const & params )

computes the integral contribution of the triangular triangle, the only contribution comes from Neel surface anisotropy

Parameters

[in] params

Parameters

[in]	getter
[out]	result

◆ interpolation() [2/2]
