Neural networks for topology optimization [PDF]

open access: yesRussian Journal of Numerical Analysis and Mathematical Modelling, 2019
Abstract In this research, we propose a deep learning based approach for speeding up the topology optimization methods. The problem we seek to solve is the layout problem. The main novelty of this work is to state the problem as an image segmentation task.

Optimal transportation, topology and uniqueness [PDF]

open access: yesBulletin of Mathematical Sciences, 2011
The Monge-Kantorovich transportation problem involves optimizing with respect to a given a cost function. Uniqueness is a fundamental open question about which little is known when the cost function is smooth and the landscapes containing the goods to be transported possess (non-trivial) topology.

Topology optimization with a closed cavity exclusion constraint for additive manufacturing based on the fictitious physical model approach [PDF]

open access: yesAdditive Manufacturing, Volume 52, April 2022, 102630, 2021
This paper proposes a topology optimization method that considers the geometric constraint of no closed cavities to improve the effectiveness of additive manufacturing based on the fictitious physical model approach. First, the basic topology optimization concept and level set-based method are introduced.

Topology optimization using polytopes [PDF]

open access: yesComputer Methods in Applied Mechanics and Engineering, 2015
Meshing complex engineering domains is a challenging task. Arbitrary polyhedral meshes can provide the much needed flexibility in automated discretization of such domains. The geometric property of the polyhedral meshes such as the unstructured nature and the facial connectivity between elements makes them specially attractive for topology optimization

Topology optimization of turbulent flows [PDF]

open access: yesComputer Methods in Applied Mechanics and Engineering, 2018
Abstract The aim of this work is to present a fast and viable approach for taking into account turbulence in topology optimization of complex fluid flow systems, without resorting to any simplifying assumptions in the derivation of discrete adjoints. Topology optimization is an iterative gradient-based design process which minimizes an objective and ...
