Constructor & Destructor Documentation

◆ CElement()

openbeam::CElement::CElement	(	unsigned char	nEdges,
		const size_t	from_node_id,
		const size_t	to_node_id
	)

protected

Special case that initializes the first two conected_nodes_ids

Member Function Documentation

◆ createElementByName()

static Ptr openbeam::CElement::createElementByName ( const std::string & sName )

static

Class factory from element name, or nullptr for an unknown element: Element names:

"BEAM2D_AA": CElementBeam_2D_AA
"BEAM2D_AR": CElementBeam_2D_AR
"BEAM2D_RA": CElementBeam_2D_RA
"BEAM2D_RR": CElementBeam_2D_RR
"SPRING_1D": CElementSpring
"SPRING_TORSION": CElementTorsionSpring

◆ do_mesh()

virtual void openbeam::CElement::do_mesh	(	const size_t	my_idx,
		CStructureProblem &	out_fem,
		MeshOutputInfo &	out_info,
		const MeshParams &	params
	)

pure virtual

Mesh this element into a set of (possibly) smaller ones

Implemented in openbeam::CElementTorsionSpring, openbeam::CElementSpringXY, openbeam::CElementSpringDXDYRZ, openbeam::CElementSpring, and openbeam::CBaseElementBeam.

◆ drawSVG()

virtual void openbeam::CElement::drawSVG	(	void *	_cairo_context,
		const DrawStructureOptions &	options,
		const RenderInitData &	ri,
		const DrawElementExtraParams &	draw_el_params,
		const MeshOutputInfo *	meshing_info
	)		const

pure virtual

Draws the element to a SVG Cairo context (a pointer to a Cairo::RefPtr<Cairo::Context> casted to void*), according to the passed options

Implemented in openbeam::CElementTorsionSpring, openbeam::CElementSpringXY, openbeam::CElementSpringDXDYRZ, openbeam::CElementSpring, and openbeam::CBaseElementBeam.

◆ getGlobalDoFs()

void openbeam::CElement::getGlobalDoFs ( std::vector< used_DoFs_t > & dofs ) const

Return the local DoFs transformed with the current element pose in m_global_orientation

◆ getGlobalStiffnessMatrices()

virtual void openbeam::CElement::getGlobalStiffnessMatrices ( std::vector< TStiffnessSubmatrix > & outSubMats ) const

virtual

This method first calls getLocalStiffnessMatrices then rotates each matrix according to the current element orientation Can be redefined in derived classes for efficiency

◆ getLocalDoFs()

virtual void openbeam::CElement::getLocalDoFs ( std::vector< used_DoFs_t > & dofs ) const

pure virtual

Must return which DoFs are used in the returned Stiffness matrices

Implemented in openbeam::CElementTorsionSpring, openbeam::CElementSpringXY, openbeam::CElementSpringDXDYRZ, openbeam::CElementSpring, openbeam::CElementBeam_2D_RR, openbeam::CElementBeam_2D_RD, openbeam::CElementBeam_2D_RA, openbeam::CElementBeam_2D_AR, and openbeam::CElementBeam_2D_AA.

◆ getLocalStiffnessMatrices()

virtual void openbeam::CElement::getLocalStiffnessMatrices ( std::vector< TStiffnessSubmatrix > & outSubMats ) const

pure virtual

Return the stiffness submatrices (for element local coordinates) between each pair of edges in this element, for the current element state. From all (in,out) edge pairs, only return those with in<=out (the other half is the corresponding transpose).

Implemented in openbeam::CElementTorsionSpring, openbeam::CElementSpringXY, openbeam::CElementSpringDXDYRZ, openbeam::CElementSpring, openbeam::CElementBeam_2D_RR, openbeam::CElementBeam_2D_RD, openbeam::CElementBeam_2D_RA, openbeam::CElementBeam_2D_AR, and openbeam::CElementBeam_2D_AA.

◆ getNumberEdges()

unsigned char openbeam::CElement::getNumberEdges ( ) const

inline

Must return the number of "ports" or "edges" of this element. This is the same than the length of conected_nodes_ids and the vectors returned by getLocalStiffnessMatrices

◆ getParent()

CFiniteElementProblem* openbeam::CElement::getParent ( ) const

inline

Get the parent FEM problem object

◆ loadParamsFromSet() [1/2]

void openbeam::CElement::loadParamsFromSet ( const mrpt::containers::yaml & p )

inline

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ loadParamsFromSet() [2/2]

virtual void openbeam::CElement::loadParamsFromSet	(	const mrpt::containers::yaml &	p,
		const EvaluationContext &	ctx
	)

pure virtual

Parse a set of parameters by (casi insensitive) name and set the element values from them. Each element must document the supported parameters and their meaning.

Implemented in openbeam::CElementTorsionSpring, openbeam::CElementSpringXY, openbeam::CElementSpringDXDYRZ, openbeam::CElementSpring, and openbeam::CBaseElementBeam.

◆ setDesignRotationAroundLinearAxis()

void openbeam::CElement::setDesignRotationAroundLinearAxis ( num_t ang )

inline

For linear elements from i->j, there's a rotation which is undefined if they're fixed between any two points. This parameter model that rotation. It's used during updateOrientationFromNodePositions

◆ updateOrientationFromNodePositions()

virtual void openbeam::CElement::updateOrientationFromNodePositions ( )

virtual

Updates m_global_orientation from the global poses of conected_nodes_ids and the value m_design_rotation_around_linear_axis

Member Data Documentation

◆ conected_nodes_ids

std::vector<size_t> openbeam::CElement::conected_nodes_ids

The list of connected nodes at each "port" or "face" It's set to the correct size at constructions automatically.
