chrono::fea::ChContactSurfaceSegmentSet Class Reference

Description

Class which defines a contact surface for FEA elements.

Suitable for cable and beam elements, it uses one or more capsules per element (depending on the number of nodes).

AddAllSegments()

void chrono::fea::ChContactSurfaceSegmentSet::AddAllSegments

(

double

sphere_swept = 0.0

)

Utility function to add segments for all 1D elements of the associated FEA mesh to this collision set.

This function does nothing if the contact surface was not yet associated with an FEA mesh.

AddSegment() [1/2]

void chrono::fea::ChContactSurfaceSegmentSet::AddSegment	(	std::shared_ptr< ChNodeFEAxyz >	node1,
		std::shared_ptr< ChNodeFEAxyz >	node2,
		bool	owns_node1,
		bool	owns_node2,
		double	sphere_swept = 0.0
	)

Add the segment specified by the two given XYZ nodes to this contact surface.

Parameters

node1	segment node1
node2	segment node2
owns_node1	collision segment owns node1
owns_node2	collision segment owns node2
sphere_swept	thickness (radius of sweeping sphere)

AddSegment() [2/2]

void chrono::fea::ChContactSurfaceSegmentSet::AddSegment	(	std::shared_ptr< ChNodeFEAxyzrot >	node1,
		std::shared_ptr< ChNodeFEAxyzrot >	node2,
		bool	owns_node1,
		bool	owns_node2,
		double	sphere_swept = 0.0
	)

Add the segment specified by the two given XYZRot nodes to this contact surface.

Parameters

node1	segment node1
node2	segment node2
owns_node1	collision segment owns node1
owns_node2	collision segment owns node2
sphere_swept	thickness (radius of sweeping sphere)
