Application of free mesh method to fluid analysis (A highehr-order free mesh method and its application to a nonlinear problem)

摘要

In this paper, free Mesh Method (a kind of meshless method) proposed by the authors is imporved for application to steady incompressible viscous flow analysis. In the finite-element analysis of incompressible viscous flow, it is better to use different-order interpolation function for velocity and pressure. In the method, quadratic interpolation function can be used by introducing be assembled independently node-by-node.
