Graph Neural Networks for Mesh Generation and Adaptation in Structural and Fluid Mechanics

Autor: Ugo Pelissier, Augustin Parret-Fréaud, Felipe Bordeu, Youssef Mesri

Publikováno v: Mathematics, Vol 12, Iss 18, p 2933 (2024)

The finite element discretization of computational physics problems frequently involves the manual generation of an initial mesh and the application of adaptive mesh refinement (AMR). This approach is employed to selectively enhance the accuracy of r

Part and supports optimization in metal powder bed additive manufacturing using simplified process simulation

Autor: Martin Bihr, Grégoire Allaire, Xavier Betbeder-Lauque, Beniamin Bogosel, Felipe Bordeu, Julie Querois

This paper is concerned with shape and topology optimization of parts and their supports, taking into account constraints coming from the metal powder bed additive manufacturing process. Despite the high complexity of this process, it is represented

A nonintrusive distributed reduced‐order modeling framework for nonlinear structural mechanics—Application to elastoviscoplastic computations

Autor: David Ryckelynck, Nissrine Akkari, Felipe Bordeu, Fabien Casenave, Christian Rey

Publikováno v: International Journal for Numerical Methods in Engineering
International Journal for Numerical Methods in Engineering, Wiley, 2019, 121 (1), pp.32-53. ⟨10.1002/nme.6187⟩

In this work, we propose a framework that constructs reduced order models for nonlinear structural mechanics in a nonintrusive fashion, and can handle large scale simulations. We identify three steps that are carried out separately in time, and possi

International audience; Hadamard's method of shape differentiation is applied to topology optimization of a weakly coupled three physics problem. The coupling is weak because the equations involved are solved consecutively, namely the steady state Na

Parametric 3D elastic solutions of beams involved in frame structures

Autor: Beatrice Carles, Chady Ghnatios, Damien Sireude, Daniel Boulze, Felipe Bordeu, Adrien Leygue, Francisco Chinesta

Publikováno v: Advances in aircraft and spacecraft science. 2:233-248

Frame structures have been traditionally represented as an assembling of components, these last described within the beam theory framework. In the case of frames involving complex components in which classical beam theory could fail, 3D descriptions

Arlequin based PGD domain decomposition

Autor: S. Mohamed Nazeer, Felipe Bordeu, Adrien Leygue, Francisco Chinesta

Publikováno v: Computational Mechanics. 54:1175-1190

Problems defined in fully or partially separable domains can be solved by considering a space separated representation of the unknown fields. Thus three-dimensional problems can be solved from the solution of some one-dimensional problems in the case

Publikováno v: International Journal for Numerical Methods in Biomedical Engineering. 29:586-600

We introduce here a novel approach for the numerical simulation of nonlinear, hyperelastic soft tissues at kilohertz feedback rates necessary for haptic rendering. This approach is based upon the use of proper generalized decomposition techniques, a

We analyse here how Dynamic Data Driven Application Systems (DDDAS) can constitute a valuable tool in the field of forming processes. Simulation tools in the field of DDDAS are required to provide a response in real-time, a requisite that is often to

Journal of Computational Surgery, 2014, 1 (1), pp.1-14. ⟨10.1186/2194-3990-1-1⟩

Simulation of all phenomena taking place in a surgical procedure is a formidable task that involves, when possible, the use of supercomputing facilities over long time periods. However, decision taking in the operating room needs for fast methods tha
