Boundary particle method

边界粒子法（边界粒子法是一种无需内部布点的边界型无网格方法，适用于计算非齐次偏微分方程，具有谱收敛、数学简单、编程容易、矩阵对称等优点。仅需边界布点，适用于计算仅部分边界数据可测的数学物理反问题，具有固有优势）

边界粒子法

...豆丁网与边界积分方程相结合，先后提出了边界节点法（boundary node method，BNM）， 边界粒子法（boundary particle method，BPM）等无网格法，并且将其应用到位势问题中去，但该方法仍需要在全局边界上积分，而且刚度矩阵仍然是不对称...

abstract: In applied mathematics, the boundary particle method (BPM) is a truly boundary-only meshless (meshfree) collocation technique, in the sense that none of inner nodes are required at all in the numerical solution of nonhomogeneous partial differential equations. Numerical experiments also show that the BPM has spectral convergence.
