Research progress of RBF dynamic mesh technology and its application in aeroelasticity
摘要
Abstract
In multidisciplinary coupled calculations represented by aeroelastic calculations,structural deformation will lead to deformation of the fluid solution domain.It is necessary to develop a dynamic mesh deformation technology with good versatility,high computational efficiency and strong applicability to meet the calculation needs of aerody-namic forces.The dynamic mesh technology based on the Radial Basis Function(RBF)interpolation method has strong deformation ability and is applicable to the deformation calculation of any type of mesh.It is considered to be a dynamic mesh technology with good application prospects.This article introduces the basic theory of dynamic mesh technology based on RBF,and analyzes the selection scheme of basis function and compact radius of RBF.The re-search progress of acceleration algorithm and accuracy improvement method for mesh deformation technology based on RBF is summarized,and the hybrid dynamic mesh technology based on RBF is introduced.A brief summary of the current research status of RBF-based dynamic mesh technology in aeroelastic calculations is also made.关键词
