Pure Rust BEM (Boundary Element Method) Solver

This module provides a complete BEM solver for acoustic scattering problems, supporting Traditional BEM (TBEM), Single-Level Fast Multipole (SLFMM), and Multi-Level Fast Multipole (MLFMM) methods.

Architecture

• types: Core data structures (Mesh, Element, PhysicsParams)
• constants: Physical and integration constants
• greens: Green’s function computations (Helmholtz kernel)
• mesh: Mesh loading, element operations, and mesh generators
• integration: Numerical quadrature (Gauss-Legendre, singular)
• assembly: BEM matrix assembly (TBEM, SLFMM, MLFMM)
• solver: Linear solvers (Direct, CGS, BiCGSTAB)
• incident: Incident field computation (plane waves, point sources)
• postprocess: Result computation at evaluation points
• io: Input/output (NC.inp format, JSON)
• bem_solver: High-level API for solving BEM problems
