Design and implementation of visual system for finite element model with tens of millions of nodes based on SiPESC platform

A high performance visual system for finite element model (FEM) with tens of millions of nodes is implemented, and the relevant algorithms, data structures, key techniques and software design framework are presented. Through the analyses of the features of 3D FEM and the general FEM visual system SiPESC.POST, the internal elements culling technology and refined data structures based on topology structure are proposed. And then, in conjunction with VBO rapid display technology, the developed visual system displays the FEM with tens of millions of nodes smoothly. Compared with several large commercial FEM software systems, the proposed system demonstrates its superiority in visual efficiency and feasibility for super large-scale problems.
