LAPLACE'S equationDIRICHLET problemNUMERICAL analysisDECOMPOSITION (Mathematics)The method of fundamental solutions (MFS) was first used by Kupradze in 1963. Since then, there have appeared numerous reports of the MFS. Most of the existing analysis for the MFS are confined to Dirichlet problems on ...
InteriorConstraint 的第一个参数是方程表达式,用于描述如何计算约束目标,此处填入在 3.2 方程构建 章节中实例化好的 equation["laplace"].equations; 第二个参数是约束变量的目标值,在本问题中我们希望 Laplace 方程产生的结果 laplace 被优化至 0,因此将它的目标值全设为 0; 第三个参数是约束方程作用的计算域,此...
Numerical solutions for the two-dimensional Laplace equation using isosceles right triangular cell-centred and square control volumes are compared in this work. The methodology employed for the square grids is the one related to unstructured grids, while for the square volumes the discretization process...
