Automated CAD model simplification plays an important role in effectively utilizing physics-
based simulation during the product realization process. Currently a rich body of literature …

In spite of the widespread use of CAD systems for design and CAE systems for analysis, the
two processes are not well integrated because CAD and CAE models inherently use …

This paper presents a novel compact adjacency‐based topological data structure for finite
element mesh representation. The proposed data structure is designed to support, under the …

Recently, three-dimensional CAD systems based on feature-based solid modeling
techniques have been widely used for product design. However, when part models …

It is well-known that the Voronoi diagram of points and the power diagram for weighted
points, such as spheres, are cell complexes, and their respective dual structures, ie the …

Given a set of spheres in 3D, constructing its Voronoi diagram in Euclidean distance metric
is not easy at all even though many mathematical properties of its structure are known. This …

A simplified geometric model with lower dimensionality, such as a mid-surface model, is
often preferred over a detailed solid model for the analysis process, if the analysis results …

This paper proposes a new feature-based multiresolution modeling approach that can
provide multiresolution representation of dynamically changing CAD models of intermediate …

Euclidean Voronoi diagram of spheres in 3-dimensional space has not been explored as
much as it deserves even though it has significant potential impacts on diverse applications …

At the initial stage of ship design, it is difficult for designers to define all design information of
a hull structure on 2D drawings. Thus, other designers must undertake the arduous task of …
