Journal ArticleDOI
The characteristic-based-split procedure: an efficient and accurate algorithm for fluid problems
TL;DR: It turns out that the characteristic-based-split (CBS) process allows equal interpolation to be used for all system variables without difficulties when the incompressible or nearly incompressable stage is reached.
Journal ArticleDOI
Alya: Multiphysics engineering simulation toward exascale
Mariano Vázquez,Mariano Vázquez,Guillaume Houzeaux,Seid Koric,Antoni Artigues,Jazmin Aguado-Sierra,Ruth Arís,Daniel Mira,Hadrien Calmet,Fernando M. Cucchietti,Herbert Owen,Ahmed Taha,Evan Dering Burness,José María Cela,Mateo Valero +14 more
TL;DR: Alya's main features are introduced and focus particularly on its solvers and the performance up to 100.000 processors in Blue Waters, the NCSA supercomputer with selected multi-physics tests that are representative of the engineering world.
Journal ArticleDOI
A parallel finite-element method for three-dimensional controlled-source electromagnetic forward modelling
Vladimir Puzyrev,Jelena Koldan,Josep de la Puente,Guillaume Houzeaux,Mariano Vázquez,José María Cela +5 more
TL;DR: A nodal finite-element method that can be used to compute in parallel highly accurate solutions for 3-D controlled-source electromagnetic forward-modelling problems in anisotropic media and demonstrates the performance in large problems with tens and even hundreds of millions of degrees of freedom.
Journal ArticleDOI
A general algorithm for compressible and incompressible flows. Part III: The semi‐implicit form
TL;DR: In this article, the authors consider the semi-implicit version of a fractional step finite element method for compressible flows and show that no boundary conditions at all need to be imposed in the first step where an intermediate momentum is computed.
Journal ArticleDOI
A massively parallel fractional step solver for incompressible flows
TL;DR: This paper presents a parallel implementation of fractional solvers for the incompressible Navier-Stokes equations using an algebraic approach and the implementation of the mesh partitioning technique is presented, as well as the parallel performances and speedups for thousands of processors.
