| Abstract: |
| In this paper,node-based local mesh generation(NLMG) algorithms designed for the node-based finite element method are discussed.A new idea is put forward to circumvent the so-called inconsistency phenomenon which probably occurring in the NLMG process in virtue of the uniqueness of the global partition algorithm for the given nodes.As an application,Localized Repartition Delaunay triangulation algorithm is suggested and shown to be valuable and efficient based on both the theory analysis and numerical examples results.The key step of NLMG algorithms,i.e.the determination of the radius of searching circle,is achieved through repartitioning the domain of analysis,which can be realized easily and has low complexity in algorithms. |
