A reinforcement learning approach to airfoil shape optimization. [PDF]
Sci Rep, 2023 Shape optimization is an indispensable step in any aerodynamic design. However, the inherent complexity and non-linearity associated with fluid mechanics as well as the high-dimensional design space intrinsic to such problems make airfoil shape ...

One-2-3-45: Any Single Image to 3D Mesh in 45 Seconds without Per-Shape Optimization [PDF]
Neural Information Processing Systems, 2023 Single image 3D reconstruction is an important but challenging task that requires extensive knowledge of our natural world. Many existing methods solve this problem by optimizing a neural radiance field under the guidance of 2D diffusion models but ...

Aeroacoustic airfoil shape optimization enhanced by autoencoders [PDF]
Expert systems with applications, 2022 We present a framework for airfoil shape optimization to reduce the trailing edge noise for the design of wind turbine blades. Far-field noise is evaluated using Amiet's theory coupled with the TNO-Blake model to calculate the wall pressure spectrum and ...

A novel p-harmonic descent approach applied to fluid dynamic shape optimization [PDF]
Structural And Multidisciplinary Optimization, 2021 We introduce a novel method for the implementation of shape optimization for non-parameterized shapes in fluid dynamics applications, where we propose to use the shape derivative to determine deformation fields with the help of the p-\documentclass[12pt]{

On Convergence in Elliptic Shape Optimization [PDF]
SIAM Journal on Control and Optimization, 2007 This paper is aimed at analyzing the existence and convergence of approximate solutions in shape optimization. Two questions arise when one applies a Ritz-Galerkin discretization to solve the necessary condition: does there exists an approximate solution and how good does it approximate the solution of the original infinite dimensional problem?

SDFDiff: Differentiable Rendering of Signed Distance Fields for 3D Shape Optimization [PDF]
Computer Vision and Pattern Recognition, 2019 We propose SDFDiff, a novel approach for image-based shape optimization using differentiable rendering of 3D shapes represented by signed distance functions (SDFs). Compared to other representations, SDFs have the advantage that they can represent shapes
