multipole expansion method

基本解釋

By comparison with ANSYS, it was clear that BEM could solve the problem not only effectively but also precisely. In chapter 3, the theory of Multipole Expansion Method is introduced.
第3 章著重介紹了多極展開法的基本理論知識(shí)，為多極展開法與邊界元法的結(jié)合奠定理論基礎(chǔ)。
The three-dimensional boundary element method for elastic materials was extended to develop a fast multipole expansion formulation of the fundamental solutions for quadratic elements.
在三維彈性力學(xué)邊界元法的基礎(chǔ)上，推導(dǎo)出二階單元的基本解快速多極展開格式。
