Struct Truss 

pub struct Truss {
    pub node_i: NodeId,
    pub node_j: NodeId,
    pub area: f64,
    pub material: Material,
    pub density: f64,
}

A 2-node axial truss: fixed-size element-local linear algebra, no heap allocation in the hot path. Only ever populates the translational DOF entries of the (3-DOF-per-node) local/global matrices; the rotation entries stay zero. Its dof_mask is therefore translations only, so a node connected only to trusses has no rotation unknown and the model need not fix it.

Fields

node_i: NodeId

node_j: NodeId

area: f64

material: Material

density: f64

Mass per unit volume. Zero (the default) means massless — existing models are unaffected unless they opt in via with_density.

Implementations

impl Truss

pub fn new( node_i: NodeId, node_j: NodeId, area: f64, material: Material, ) -> Self

pub fn with_density(self, density: f64) -> Self

Trait Implementations
