Description: 边界节点法(Boundary Knot Method)是一种被广泛使用的无网格数值方法，具有编程容易、收敛速度快等优点，被广泛关注。边界节点法的主要思想是利用控制方程的非奇异一般解的线性组合来近似方程的解，通过配点法求解出未知系数。在这整个计算过程中保持了无网格的优势。鉴于边界节点法的优点，作者开发了基于边界节点法的MATLAB工具箱用以求解一些常见的椭圆形方程控制的物理问题如Helmholtz方程控制的声学问题等，为科学研究和工程应用提供了一个简便的工具。本软件可用于科学研究和实际工程计算，为各种实际工程提供有力的数值计算结果，也为广大的学者理解无网格方法提供了一些帮助。-Boundary knot method (Boundary Knot Method) is an meshless numerical methods are widely used, with programming easy, fast convergence, etc., has been widespread concern. The main idea of boundary knot method is to use a combination of non-linear singular general solution of equations to approximate solution of the equation by the collocation method for solving the unknown factor. Maintained without grid computing advantage in this whole process. Given the advantages of the boundary knot method, the authors developed a method based on boundary nodes MATLAB toolbox for solving some of the physical problems common elliptic equation control acoustic problems such as control of the Helmholtz equation, etc., for scientific research and engineering applications provide a simple Tool of. This software can be used for scientific research and practical engineering calculations, provide a powerful numerical results for a variety of practical projects, but also provides some help for Platform: |
