Struct PyFemBinding 

pub struct PyFemBinding { /* private fields */ }

PyO3-style binding handle for a 2-D FEM solver.

Wraps PyFemSolver and PyFemMesh and exposes helpers suitable for future #[pymethods] annotation.

Implementations

impl PyFemBinding

pub fn new() -> Self

Create a new FEM binding with an empty mesh.

pub fn add_node(&mut self, x: f64, y: f64) -> usize

Add a 2-D node at position (x, y). Returns the new node index.

pub fn add_tri_element(&mut self, n0: usize, n1: usize, n2: usize) -> usize

Add a CST triangular element given three node indices.

Returns the new element index.

pub fn add_tri_element_with_material( &mut self, n0: usize, n1: usize, n2: usize, material_id: usize, thickness: f64, ) -> usize

Add a CST triangular element with explicit material and thickness.

pub fn add_material(&mut self, material: PyFemMaterial) -> usize

Add a material to the mesh library. Returns the material index.

pub fn node_count(&self) -> usize

Return the number of nodes.

pub fn element_count(&self) -> usize

Return the number of elements.

pub fn pin_node(&mut self, node: usize)

Pin a node (fix both x and y DOFs to zero).

pub fn add_dirichlet_bc(&mut self, bc: PyFemDirichletBC)

Apply a Dirichlet (fixed DOF) boundary condition.

pub fn apply_nodal_force(&mut self, node: usize, fx: f64, fy: f64)

Apply a nodal force [fx, fy] at node.

pub fn solve(&mut self) -> bool

Solve the linear-elastic static problem.

Returns true on success. Query results via get_displacement_flat.

pub fn get_displacement_flat(&self) -> Vec<f64>

Return nodal displacements as a flat [ux0,uy0, ux1,uy1, …] array, or an empty Vec if no solve has been run.

pub fn get_stress_flat(&self) -> Vec<f64>

Return element von-Mises stresses as a flat array.

pub fn max_von_mises_stress(&self) -> f64

Return the maximum von-Mises stress, or 0.0 if no result exists.

pub fn last_solve_converged(&self) -> bool

Return whether the last solve converged.
