基于STL模型的砂型表面网格重构算法
Surface Mesh Reconstruction Algorithm of Sand Mold Based on STL Model
摘要
Abstract
To solve the problem of local mesh sparseness when generating surface meshes for STL models by general simulation software,this article proposed a surface mesh reconstruction algorithm for sand mold based on the STL model.This algorithm encrypted the feature boundary of the generated surface mesh and the interior of the surface mesh,which could effectively solve the problems of low density and quality of the surface mesh as well as inability to perform finite element simulation.An example simulation was carried out based on ProCAST simulation software,and the result verified the feasibility of STL mesh model simulation after surface mesh reconstruction.关键词
