📢 Artelys est heureux de collaborer une nouvelle fois avec Grenoble-Alpes Métropole pour la révision de son schéma directeur des énergies, après avoir réalisé la première version en 2017 ! L’objectif de l’étude est d’identifier le meilleur mix énergétique pour atteindre la neutralité carbone d’ici 2050 en visant un usage optimal des réseaux énergétiques métropolitains. Grenoble Alpes Métropole s'inscrit ainsi parmi les métropoles précurseurs en étudiant finement l'impact des scénarios de transition énergétique sur les réseaux de distribution d'électricité, de gaz et de chaleur afin d'anticiper au mieux l'évolution de son système énergétique. 💡 Pour y parvenir, Artelys s'appuiera sur ses compétences éprouvées en planification énergétique - et son logiciel dédié Artelys Crystal City - ainsi que sur sa large expertise en modélisation et simulation des réseaux de distribution d'énergie. 💪 Dans ce projet, nous sommes ravis de travailler une fois encore avec AEC qui apporte son expertise économique, notamment sur l'avenir des réseaux de distribution de gaz.

Nonlinear programming is a fundamental paradigm to solve optimization problems. We just published two additional notebooks on our Github account: https://lnkd.in/d-aaHbEi to illustrate what can be done with nonlinear programming. If you're interested to see what nonlinear programming can be used for, do not hesitate to check them out. The first notebook is about the well-know k-means clustering problem and its variants. 👉https://lnkd.in/dwWNCJPr The second notebook shows a facility layout problem. 👉https://lnkd.in/dYfRWXfU You can read the notebooks online or request a trial licence of Artelys Knitro to run them on your own machine. Do not hesitate to check the other notebooks as well👇

📣 The #CIGRE2024 kicks off in less than a week! Artelys will be present throughout the event, so don't hesitate to visit our stand (S1P38) and have a chat with our experts!

👀 Read how Artelys Knitro is used in the design of deployable structures in this article from ACM Transactions on Graphics. Deployable structures typically consist of rigid elements connected via rotational joints which have compact rest states and deploy into 3D target surfaces. Such structures are widely used in industrial and consumer products, medical devices, aerospace applications, and civil installations. The authors propose a new deployable material system, called umbrella mesh, that combines rigid linkage mechanisms and elastic beams to enable a wide variety of shapes. Umbrella meshes are composed of regular arrangements of parameterized cells. All cells cover the same area footprint, but the differing cell heights cause this area to expand by different amounts during deployment and result in a curved shape. The authors provide a model to simulate the deployment of such structures and present an algorithm to optimize the free design parameters to best approximate a given target shape. These results are validated with physical prototypes and show that umbrella meshes allow to obtain surface geometries that are not possible with other existing methods. The authors rely on Artelys Knitro to determine the optimal shape parameters for approximating a given target surface. The optimization problem is nonlinear, and the Artelys Knitro interior-point Conjugate gradient algorithm is exploited to rapidly converge to an optimal design.
