Mixed aggregated finite element methods for the unfitted discretization of the Stokes problem
(2018-12-18)
Article
Accés obertIn this work, we consider unfitted finite element methods for the numerical approximation of the Stokes problem. It is well-known that these kinds of methods lead to arbitrarily ill-conditioned systems and poorly approximated ... -
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 ... -
Numerical modelling of heat transfer and experimental validation in powder-bed fusion with the virtual domain approximation
(2020-01)
Article
Accés obertAmong metal additive manufacturing technologies, powder-bed fusion features very thin layers and rapid solidification rates, leading to long build jobs and a highly localized process. Many efforts are being devoted to ... -
On a general implementation of h- and p-adaptive curl-conforming finite elements
(2019-06)
Article
Accés obertEdge (or Nédélec) finite elements are theoretically sound and widely used by the computational electromagnetics community. However, its implementation, especially for high order methods, is not trivial, since it involves ... -
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 ... -
Physics-based balancing domain decomposition by constraints for multi-material problems
(2019-05)
Article
Accés obertIn this work, we present a new variant of the balancing domain decomposition by constraints preconditioner that is robust for multi-material problems. We start with a well-balanced subdomain partition, and based on an ... -
Scalable solvers for complex electromagnetics problems
(2019-09)
Article
Accés obertIn this work, we present scalable balancing domain decomposition by constraints methods for linear systems arising from arbitrary order edge finite element discretizations of multi-material and heterogeneous 3D problems. ... -
Simulation of high temperature superconductors and experimental validation
(2019-04)
Article
Accés obertIn this work, we present a parallel, fully-distributed finite element numerical framework to simulate the low-frequency electromagnetic behaviour of superconducting devices, which efficiently exploits high performance ... -
Symmetric rank-k update on clusters of multicore processors with SMPSs
(IOS Press, 2011)
Comunicació de congrés
Accés obertWe investigate the use of the SMPSs programming model to leverage task parallelism in the execution of a message-pas sing implementation of the symmetric rank- k update on clusters equipped with multicore processors. Our ... -
The aggregated unfitted finite element method for elliptic problems
(2018-07)
Article
Accés obertUnfitted finite element techniques are valuable tools in different applications where the generation of body-fitted meshes is difficult. However, these techniques are prone to severe ill conditioning problems that obstruct ...
