Adjoint-Based Low-Boom Design with Cart3D
We consider analysis and design of low sonic-boom aircraft through the use of an inviscid, embedded-boundary Cartesian mesh method. Adjoint error estimation and adaptive meshing are used in the analysis portion of this study to determine resolution requirements of the computational domain, while adjoint-based gradients in conjunction with a parallel optimization framework are used for design. T...
متن کاملAdjoint Code Design Patterns
Adjoint methods have become fundamental ingredients of the scientific computing toolbox over the past decades. Large-scale parameter sensitivity analysis, uncertainty quantification and nonlinear optimization as well as modern approaches to deep learning would otherwise turn out computationally infeasible. For nontrivial real-world problems the algorithmic derivation of adjoint numerical simula...
متن کاملA Novel Formulation of the Adjoint Method in the Optimal Design of Quantum Electronic Devices
The adjoint method is used to efficiently and accurately compute gradients with respect to the design parameters in the identification of optimal designs of electronic devices whose physical behavior is determined by solutions of the Schrödinger equation. In this study, the optimal design problem is formulated as the minimization of a least-squares performance metric. Key to our approach is the...
متن کاملAdjoint-based Shape Sensitivities for Turbomachinery Design Optimizations
An adjoint preprocess for an adjoint-based turbomachinery design process is described. The resulting process is compared to a previously established adjoint process based on three-dimensional adjoint solutions and deformed meshes. Within the new process, the calculation of sensitivities is performed using shape sensitivities and surface displacements, where the design parameters are computer-ai...
متن کاملModel-based design of haptic devices
Efficient engineering design and development of high precision and reliable surgical simulators, like haptic devices for surgical training benefits from model-based and simulation driven design. The complexity of the design space, multi-domains, multicriteria requirements and multi-physics character of the behavior of such a product ask for a model based systematic approach for creating and val...
