1//! Multigrid FEM solver for Helmholtz equation
2//!
3//! This crate provides a finite element method solver for the Helmholtz equation
4//! with adaptive mesh refinement and multigrid acceleration.
5//!
6//! # Features
7//!
8//! - **2D and 3D meshes**: Triangles, quadrilaterals, tetrahedra, hexahedra
9//! - **Lagrange elements**: P1, P2, P3 polynomial basis functions
10//! - **Boundary conditions**: Dirichlet, Neumann, Robin, PML
11//! - **Multigrid solver**: V-cycle, W-cycle with geometric coarsening
12//! - **Adaptive refinement**: h-refinement with residual-based error estimation
13//!
14//! # Example
15//!
16//! ```ignore
17//! use math_audio_fem::{FemProblem, FemSolver, mesh};
18//!
19//! // Create a 2D mesh
20//! let mesh = mesh::unit_square_triangles(10);
21//!
22//! // Define the Helmholtz problem
23//! let problem = FemProblem::helmholtz(mesh, k);
24//!
25//! // Solve
26//! let solver = FemSolver::new();
27//! let solution = solver.solve(&problem)?;
28//! ```
