چکیده
Automatic diierentiation (AD) is a technique for augmenting computer codes to compute derivatives of a subset of their outputs with respect to a subset of their inputs. AD has been shown to provide accurate, but ineecient, sensitivity-enhanced CFD codes for use in aerodynamic shape optimization. To address the ineeciency problem, several special purpose techniques have been suggested. One such technique is the incremental iterative (II) method. This report describes and evaluates the use of the II method in AD-augmented code for OVERFLOW, a parallel, multigrid CFD code.

This paper is devoted to optimal sizing. As a model example we consider the minimization of the mass of the frame of an injection moulding machine. The deformation of the frame is described by a generalized plane stress state with an elasticity modulus scaled by the thickness. This constrained nonlinear optimization problem is solved by sequential quadratic programming (SQP) which requires grad...

The streamlines in a 2-D contraction were calculated through solving the potential flow equations in rectangular and curvilinear coordinates. The natural cubic...
متن کاملComputing Gradients in Large-Scale Optimization Using Automatic Differentiation
The accurate and eecient computation of gradients for partially separable functions is central to the solution of large-scale optimization problems, since these functions are ubiquitous in large-scale problems. We describe two approaches for computing gradients of partially separable functions via automatic diierentiation. In our experiments we employ the ADIFOR (Automatic Diierentiation of For...
