Struct Orientation 

pub struct Orientation { /* private fields */ }

Local axes of a zero-length element, built the OpenSees way. In 3D that is -orient x1 x2 x3 yp1 yp2 yp3: local x is x, local z is x × yp, and local y is z × x. In 2D OpenSees takes only x (see in_plane) and derives y by a 90 degree turn. Every per-DOF material (and a section’s axial and flexural directions) is then evaluated on the relative displacement and rotation projected onto these axes rather than the global ones. Without an orientation the local axes are the global axes.

Translations and rotations share one frame, as in OpenSees: local rz is the rotation about the local z axis, and so on.

Implementations

impl Orientation

pub fn global() -> Self

pub fn new(x: [f64; 3], yp: [f64; 3]) -> Result<Self, OrientationError>

pub fn in_plane(x1: f64, x2: f64) -> Result<Self, OrientationError>

OpenSees’ 2D -orient x1 x2: local x is (x1, x2) and local y is that vector turned 90 degrees counter-clockwise, so the frame is always right-handed about z and local rz is global rz.
