Journal ArticleDOI
A new Approach to Variable-Topology Shape Design Using a Constraint on the Perimeter
TL;DR: The perimeter method as mentioned in this paper allows the designer to control the number of holes in the optimal design and to establish their characteristic length scale, thus eliminating the need for relaxation, thereby circumventing many of the complexities and restrictions of other approaches to topology design.
Journal ArticleDOI
Topology optimization of channel flow problems
TL;DR: In this article, the authors consider steady, incompressible laminar viscous flows at low-to-moderate Reynolds numbers and use the finite element method to model the flow, and solve the optimization problem with a gradient-based math-programming algorithm that is driven by analytical sensitivities.
Journal ArticleDOI
Stability of finite element models for distributed-parameter optimization and topology design
TL;DR: A theoretical framework is presented to explain the cause of grid-scale anomalies in the numerical solutions to optimization problems, similar to those that are sometimes encountered in mixed formulations of the Stokes problem.
Journal ArticleDOI
An Analytical Model to Predict Optimal Material Properties in the Context of Optimal Structural Design
Journal ArticleDOI
A general two‐dimensional, graphical finite element preprocessor utilizing discrete transfinite mappings
TL;DR: A two-dimensional preprocessor program utilizing the discrete transfinite mappings for automated mesh generation is described and a specialized graphical ‘attribute editor’ for structural mechanics problems is also described.
