Expand description

A FEM mesh with element connectivity and material parameters.

Elements are 2-node bar/rod elements. Each element connects two nodes. Global DOF count equals the number of nodes.

Fields§

§node_coords: Vec<f64>

Node coordinates (one per node).

§elements: Vec<usize>

Element connectivity: [node_a0, node_b0, node_a1, node_b1, …].

§youngs_modulus: Vec<f64>

Young’s modulus for each element.

§area: Vec<f64>

Cross-sectional area for each element.

§k_global: Vec<f64>

Global stiffness matrix (n_dofs × n_dofs, row-major).

§displacements: Vec<f64>

Global displacement vector (n_dofs).

§ext_forces: Vec<f64>

Global external force vector (n_dofs).

§residual: Vec<f64>

Residual vector r = f − K·u (n_dofs).

§dirichlet_flags: Vec<bool>

Dirichlet (fixed) DOF flags: true means constrained.

Implementations§

Source §

impl GpuFemMesh

Source

pub fn new(node_coords: Vec<f64>, elements: Vec<usize>) -> Self

Create a new GpuFemMesh from node coordinates and element connectivity.

elements must be a flat list of node-index pairs [a0, b0, a1, b1, …]. All material parameters default to 1.0.

Source

pub fn n_dofs(&self) -> usize

Number of nodes (= DOFs for 1-D bar formulation).

Source

pub fn n_elements(&self) -> usize

Number of elements.
