4//! Finite element method for the OxiPhysics engine.
5//!
6//! Provides a complete linear elastic FEM pipeline including:
7//!
8//! - **Sparse matrix** types ([`sparse::CsrMatrix`], [`sparse::SparseVector`])
9//! - **Mesh** representation ([`mesh::TetrahedralMesh`]) with beam generation
10//! - **Element** formulation ([`element::LinearTetrahedron`]) for 4-node tetrahedra
11//! - **Constitutive** models ([`constitutive::LinearElasticMaterial`])
12//! - **Assembly** of global stiffness and load vectors
13//! - **Boundary conditions** (Dirichlet and Neumann)
14//! - **Iterative solvers** (CG, preconditioned CG)
15//! - **Static analysis** driver ([`analysis::LinearStaticAnalysis`])
