Constructor & Destructor Documentation

chrono::fea::ChExtruderBeamIGA::ChExtruderBeamIGA	(	ChSystem *	msystem,
		std::shared_ptr< ChMesh >	mmesh,
		std::shared_ptr< ChBeamSectionCosserat >	sect,
		double	mh,
		const ChCoordsys<>	moutlet,
		double	mspeed,
		int	morder
	)

Initialize and add required constraints to system.

Parameters

msystem	system to store the constraints
mmesh	mesh to store the resulting elements
sect	section material for beam elements
mh	element length
moutlet	outlet pos & orientation (x is extrusion direction)
mspeed	speed
morder	element order, default =3 (cubic)

void chrono::fea::ChExtruderBeamIGA::SetContact	(	std::shared_ptr< ChMaterialSurfaceSMC >	mcontact_material,
		double	mcontact_radius
	)

Set the material for the beam, and enables collision detection for the beam nodes.

By default, collision not enabled.

Parameters

mcontact_material	material to use for surface
mcontact_radius	radius of colliding spheres at each node (usually = to avg.beam thickness)

bool chrono::fea::ChExtruderBeamIGA::Update ( )

Create beam elements, as needed, and update the constraint that imposes the extrusion speed.

Return 'true' if any new nodes/elements were created (hence a system change) and 'false' otherwise.
