A technique of transforming the variable coefficient governing equation to a constant coefficient equation is utilized for deriving a boundary integral equation. Some particular problems are considered to illustrate the application of the BEM. The results show the convergence, consistency, and accuracy of the BEM solutions. ## Keywords - Helmholtz equation - Boundary element method - Mathematical analysis - Mathematics - Boundary value problem - Convergence (economics) - Integral equation - Helmholtz free energy - Variable (mathematics) - Electric-field integral equation - Consistency (knowledge bases) - Finite element method - Geometry - Physics - Thermodynamics - Economic growth - Economics - Quantum mechanics --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
