A CAD tool connection is established to facilitate the seamless integration of structural modeling, simulation, and design optimization. A new CAD-based method for design velocity computation is proposed, applicable to both the meshfree method and the finite element method. A shape design variable can be chosen among the geometric parameters defined in the CAD model in order to support a concurrent engineering environment. A new CAD-based method for updating the discrete model is proposed, such that the meshfree model is automatically updated in a continuous and consistent way during design optimization. The proposed method is applied to 2D and 3D linear elastic problems, as well as to a large deformation hyperelastic problem.<\/jats:p>","DOI":"10.1177\/1063293x02010001056","type":"journal-article","created":{"date-parts":[[2003,7,18]],"date-time":"2003-07-18T20:58:53Z","timestamp":1058561933000},"page":"55-66","source":"Crossref","is-referenced-by-count":13,"title":["CAD-Based Shape Optimization Using a Meshfree Method"],"prefix":"10.1177","volume":"10","author":[{"given":"Iulian","family":"Grindeanu","sequence":"first","affiliation":[{"name":"Center for Computer-Aided Design and Department of Mechanical Engineering, The University of Iowa, Iowa City, IA 52242, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nam H.","family":"Kim","sequence":"additional","affiliation":[{"name":"Center for Computer-Aided Design and Department of Mechanical Engineering, The University of Iowa, Iowa City, IA 52242, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyung K.","family":"Choi","sequence":"additional","affiliation":[{"name":"Center for Computer-Aided Design and Department of Mechanical Engineering, The University of Iowa, Iowa City, IA 52242, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiun S.","family":"Chen","sequence":"additional","affiliation":[{"name":"Center for Computer-Aided Design and Department of Mechanical Engineering, The University of Iowa, Iowa City, IA 52242, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2002,3,1]]},"reference":[{"key":"bibr1-1063293X02010001056","unstructured":"Pro\/ENGINEER User's Guides, version 20.
