Struct Node 

pub struct Node<const NDIM: usize = PLANAR_NDIM, const NDOF: usize = 3> {
    pub coords: [f64; NDIM],
    pub fixed: [bool; NDOF],
    pub displacement: [f64; NDOF],
    pub velocity: [f64; NDOF],
    pub acceleration: [f64; NDOF],
    pub mass: [f64; NDOF],
}

A node in a concrete kinematic profile. Coordinates have NDIM components; state, boundary conditions, and mass have NDOF components. Node defaults to the existing planar (2, 3) profile, so its public API remains source-compatible; Node3 is the spatial (3, 6) specialization.

velocity/acceleration are only meaningful for/written by TransientAnalysis — static Analysis never touches them. Applied load is not here; it belongs to Domain load patterns because one node can carry independently scaled loads across phases.

Fields

coords: [f64; NDIM]

fixed: [bool; NDOF]

displacement: [f64; NDOF]

velocity: [f64; NDOF]

acceleration: [f64; NDOF]

mass: [f64; NDOF]

Lumped nodal mass per DOF — a user-assigned point mass, additive with any element-consistent lumped mass.
