The proposed approach is based on the conversion of the tri-mesh into T-splines [26] based on quad-meshes [27] (B), which are then automatically turned into a B-rep solid (C). Finally, meshless finite element analysis (FEA) [28] is used for the numerical simulation (D). The ...
Summary: We describe surface reconstruction algorithms based on optimization techniques. The input are scattered 3D-data with specified topology. The surfaces constructed are tensor product B-splines. To achieve local detail and/or local... G Greiner,H Kai 被引量: 158发表: 1997年 Bivariate polynom...
In this paper, a new isogeometric topology optimization (ITO) method is proposed by using T-splines based isogeometric analysis (IGA). The arbitrarily shaped design domains, directly obtained from CAD, are represented by a single T-spline surface which overcomes the topological limitations of Non-...
