A multiscale method for periodic structures using domain decomposition and ECM-hyperreduction
(2020-08-15)
Article
Accés obertThis paper presents a nonlinear multiscale approach for periodic structures in the quasi-static, small strain regime. The approach consists in combining a domain decomposition method in which interface conditions are ... -
A scalable parallel finite element framework for growing geometries: application to metal additive manufacturing
(John Wiley & sons, 2019-09)
Article
Accés obertThis work introduces an innovative parallel, fully-distributed finite element framework for growing geometries and its application to metal additive manufacturing. It is well-known that virtual part design and qualification ... -
Applications of domain decomposition techniques for the multiscale modeling of softening materials
(2009)
Text en actes de congrés
Accés obertIn this contribution we describe a methodology for the study of softening brittle materials at different scales of observation. The goal is to account for a higher resolution at those areas that undergo the non-linear ... -

Migration of a generic multi-physics framework to HPC environments
(Elsevier, 2013-07)
Article
Accés obertCreating a highly parallelizable code is a challenge specially for distributed memory machines (DMMs). Moreover, algorithms and data structures suitable for these platforms can be very different from the ones used in serial ... -
Multilevel balancing domain decomposition at extreme scales
(2016-01-01)
Article
Accés obert© 2016 Society for Industrial and Applied Mathematics. In this paper we present a fully distributed, communicator-aware, recursive, and interlevel-overlapped message-passing implementation of the multilevel balancing domain ... -
Multiscale modeling of prismatic heterogeneous structures based on a localized hyperreduced-order method
(2023-03)
Article
Accés obertThis work aims at deriving special types of one-dimensional Finite Elements (1D FE) for efficiently modeling heterogeneous prismatic structures, in the small strains regime, by means of reduced-order modeling (ROM) and ... -
Nonlinear parallel-in-time Schur complement solvers for ordinary differential equations
(2018-12)
Article
Accés obertIn this work, we propose a parallel-in-time solver for linear and nonlinear ordinary differential equations. The approach is based on an efficient multilevel solver of the Schur complement related to a multilevel time ... -
On the scalability of inexact balancing domain decomposition by constraints with overlapped coarse/fine corrections
(2015-12)
Article
Accés obertIn this work, we analyze the scalability of inexact two-level balancing domain decomposition by constraints (BDDC) preconditioners for Krylov subspace iterative solvers, when using a highly scalable asynchronous parallel ... -
Optimizing domain decomposition in an ocean model: the case of NEMO
(Elsevier, 2017)
Article
Accés obertEarth System Models are critical tools for the study of our climate and its future trends. These models are in constant evolution and their growing complexity entails an incrementing demand of the resources they require. ... -

Parallelizing general histogram application for CUDA architectures
(IEEE Computational Intelligence Society, 2013)
Text en actes de congrés
Accés restringit per política de l'editorialHistogramming is a tool commonly used in data analysis. Although its serial version is simple to implement, providing an efficient and scalable way to parallelize it can be challenging. This especially holds in case of ... -
Robust and scalable domain decomposition solvers for unfitted finite element methods
(2018-12)
Article
Accés obertUnfitted finite element methods, e.g., extended finite element techniques or the so-called finite cell method, have a great potential for large scale simulations, since they avoid the generation of body-fitted meshes and ...
