Space Deformation of Parametric Surface Based on Extension Function
parametric surface space or free-form deformation extension function
2009/8/19
In this paper, a new technique of space deformation for parametric surfaces with so-called extension function (EF) is presented. Firstly, a special extension function is introduced. Then an operator m...
Exchange of CAD Part Models Based on the Macro-Parametric Approach
CAD exchange of design intents parametric STEP
2009/8/19
It is not possible to exchange parametric information of CAD models based on the current version of STEP. The design intent can be lost during the STEP transfer of CAD models. The Parametrics Group of...
Identification of Topological Entities and Naming Mapping for Parametric CAD Model Exchanges
CAD Model Exchange Macro Parametric Naming Mapping
2009/8/19
As collaborative design and configuration design gain increasing importance in product development, it becomes essential to exchange parametric CAD models among participants. Parametric CAD models can...
Parametric Modeling and Shape Optimization of Offshore Structures
Parametric modeling shape optimization offshore structures seakeeping
2009/8/19
The paper presents an optimization system which integrates a parametric design tool, 3D diffraction-radiation analysis and hydrodynamic performance assessment based on short and long term wave statist...
Generation Of 2-D Parametric Surfaces With Highly Irregular Boundaries
2D surface boundary-conformed surface linear Coons method
2009/8/19
The conventional methods of boundary-conformed 2D surfaces generation usually yield some problems. This paper deals with two boundary-conformed 2D surface generation methods, one conventional approach...
