BuildBeam() [1/3]

void chrono::fea::ChBuilderBeamTaperedTimoshenko::BuildBeam	(	std::shared_ptr< ChMesh >	mesh,
		std::shared_ptr< ChBeamSectionTaperedTimoshenkoAdvancedGeneric >	sect,
		const int	N,
		const ChVector3d	A,
		const ChVector3d	B,
		const ChVector3d	Ydir
	)

Add beam FEM elements to the mesh to create a segment beam from point A to point B, using ChElementBeamTaperedTimoshenko type elements.

Before running, each time resets lists of beam_elems and beam_nodes.

Parameters

mesh	mesh to store the resulting elements
sect	section material for beam elements
N	number of elements in the segment
A	starting point
B	ending point
Ydir	the 'up' Y direction of the beam

BuildBeam() [2/3]

void chrono::fea::ChBuilderBeamTaperedTimoshenko::BuildBeam	(	std::shared_ptr< ChMesh >	mesh,
		std::shared_ptr< ChBeamSectionTaperedTimoshenkoAdvancedGeneric >	sect,
		const int	N,
		std::shared_ptr< ChNodeFEAxyzrot >	nodeA,
		const ChVector3d	B,
		const ChVector3d	Ydir
	)

Add beam FEM elements to the mesh to create a segment beam from one existing node to a point B, using ChElementBeamTaperedTimoshenko type elements.

Before running, each time resets lists of beam_elems and beam_nodes.

Parameters

mesh	mesh to store the resulting elements
sect	section material for beam elements
N	number of elements in the segment
nodeA	starting point
B	ending point
Ydir	the 'up' Y direction of the beam

BuildBeam() [3/3]

void chrono::fea::ChBuilderBeamTaperedTimoshenko::BuildBeam	(	std::shared_ptr< ChMesh >	mesh,
		std::shared_ptr< ChBeamSectionTaperedTimoshenkoAdvancedGeneric >	sect,
		const int	N,
		std::shared_ptr< ChNodeFEAxyzrot >	nodeA,
		std::shared_ptr< ChNodeFEAxyzrot >	nodeB,
		const ChVector3d	Ydir
	)

Add beam FEM elements to the mesh to create a segment beam from one existing node to another existing node, using ChElementBeamTaperedTimoshenko type elements.

Before running, each time resets lists of beam_elems and beam_nodes.

Parameters

mesh	mesh to store the resulting elements
sect	section material for beam elements
N	number of elements in the segment
nodeA	starting point
nodeB	ending point
Ydir	the 'up' Y direction of the beam

GetLastBeamElements()

std::vector<std::shared_ptr<ChElementBeamTaperedTimoshenko> >& chrono::fea::ChBuilderBeamTaperedTimoshenko::GetLastBeamElements ( )

inline

Access the list of elements used by the last built beam.

It can be useful for changing properties afterwards. This list is reset all times a BuildBeam function is called.

GetLastBeamNodes()

std::vector<std::shared_ptr<ChNodeFEAxyzrot> >& chrono::fea::ChBuilderBeamTaperedTimoshenko::GetLastBeamNodes ( )

inline

Access the list of nodes used by the last built beam.

It can be useful for adding constraints or changing properties afterwards. This list is reset all times a BuildBeam function is called.
