Closed Form Integration of Singular and Hypersingular Integrals in 3D BEM Formulations for Heat Conduction
Figure 15
Comparative analysis of analytical and BEM responses (real and imaginary parts) at grid 2, when null temperatures are prescribed, considering different numbers of boundary elements: (a) analytical response; (b) error using BEM (with 30 × 20 boundary elements); (c) absolute error using BEM (with 50 × 32 boundary elements).
