In this paper we present a detailed description of a high-performance distributedmemory implementation of balancing domain decomposition preconditioning techniques. This coverage provides a pool ofâ€¦ (More)

The objective of this work is to describe a variational multiscale finite element approximation for the incompressible Navier-Stokes equations using the Boussinesq approximation to model thermalâ€¦ (More)

In this work we study the performance of some variational multiscale models (VMS) in the large eddy simulation (LES) of turbulent flows. We consider VMS models obtained by different subgrid scaleâ€¦ (More)

In this work we propose a novel parallelization approach of two-level balancing domain decomposition by constraints preconditioning based on overlapping of fine-grid and coarsegrid duties in time.â€¦ (More)

In this talk we will summarize the steps we have followed towards highly scalable solver codes tailored for Finite Element (FE) analysis in our simulation software FEMPAR. In the first part of theâ€¦ (More)
