[2I15] Extension of the hierarchical-domain decomposition boundary element method to the general multi-group diffusion equation
キーワード：Boundary Element Method, HDD-BEM, Diffusion Equation, Complex Buckling
The hierarchical domain decomposition boundary element method (HDD-BEM) that was developed to solve the two-group diffusion equation and one-group SP3 equation is extended to deal with the multi-group diffusion equation. With the utilization of Python programming language, the current program can solve the one-dimensional problem with complex buckling value. By comparing it with the reference solution, the result indicates that the HDD-BEM has been extended and applied to tackle with multi-group diffusion equation successfully.
