<div class="htmlview paragraph">External aerodynamic simulations are becoming more important because of regulatory pressures on fuel economy improvements and shorter design cycles. Experimental work is typically done on scaled models to get drag and cooling flow information. This is a time consuming process.

Shape optimization using adaptive shape refinement
International Journal for Numerical Methods in Engineering, 1993AbstractA large part of the computational effort in shape optimization problems is expended in the numerical computation of the gradients for sensitivity information. This effort increases dramatically with an increase in the number of variables used to represent the shape.

Two‐dimensional shape optimal design
International Journal for Numerical Methods in Engineering, 1978AbstractThis paper treats shape optimal design of two‐dimensional structures. Sensitivity of cost and constraint functions to changes in the shape of the structure are obtained by applying theorems from the calculus of variations and by using consistent first‐order approximations of functions arising in an optimal design problem. A generalized steepest

Isogeometric Shape Optimization on Triangulations
Volume 2B: 42nd Design Automation Conference, 2016The paper presents an isogeometric shape optimization method that is based on Bézier triangles. Bézier triangles are used to represent both the geometry and physical fields. For a given physical domain defined by B-spline boundary, triangular Bézier parameterization can be automatically generated.

Multidisciplinary Shape Optimization
1986Shape optimization is expanded here beyond the specific discipline of structural synthesis to consider the spectrum of design tasks which fall into the general multidisciplinary category. This logical extension of optimization is a fruitful area of research and applications.

Abstract The selection of the optimal shape of devices in order to fulfil given prescriptions and/or to save costs, subject to various manufacturing and operational limitations and constraints, is a basic problem in all disciplines of engineering (Haslinger and Neittaanmiiki [1988]).
