Spring

Creates a spring element between two FE Points. The spring force is calculated using the following formula: F=K*(u2-u1), where K is a stiffness tensor constructed from the stiffness inputs Kx, Ky, Kz, Kxx, Kyy, and Kzz, and vector u represents the displacement at a point, which includes both translational and rotational components.

Inputs

Name	Type	Description
Point 1	FE Point	Location of FE Point.
Point 2	FE Point	Location of FE Point.
Ground point 2	Bool	Option to ground point 2. Will apply a displacement restraint in all degrees of freedom to the point.
Kx	Scalar	Stiffness value in x direction.
Ky	Scalar	Stiffness value in y direction.
Kz	Scalar	Stiffness value in z direction.
Kxx	Scalar	Stiffness value rotating around the x axis.
Kyy	Scalar	Stiffness value rotating around the y axis.
Kzz	Scalar	Stiffness value rotating around the z axis.
Frame	Frame	The reference frame for the components of the spring coefficients. If a frame is not specified, the components are in the global coordinate system.
