c_spring_element_3d Struct Reference

A three-dimensional linear, axial spring element with x, y, and z translations at each node. More...

#include <dynamics.h>

Public Attributes
double	stiffness
	The spring stiffness.
c_node	node_1
	The first node of the element.
c_node	node_2
	The second node of the element.
double	direction [3]
	The spring axis; used only if use_direction is true.
bool	use_direction
	True to define the spring axis by direction; false to define it by the vector from node_1 to node_2, in which case the nodes must not be coincident.

Detailed Description

A three-dimensional linear, axial spring element with x, y, and z translations at each node.

Member Data Documentation

stiffness

double c_spring_element_3d::stiffness

The spring stiffness.

node_1

c_node c_spring_element_3d::node_1

The first node of the element.

node_2

c_node c_spring_element_3d::node_2

The second node of the element.

direction

double c_spring_element_3d::direction[3]

The spring axis; used only if use_direction is true.

The vector must be non-zero and is normalized internally.

use_direction

bool c_spring_element_3d::use_direction

True to define the spring axis by direction; false to define it by the vector from node_1 to node_2, in which case the nodes must not be coincident.
