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
The combustion mitigation of methane as a non-CO2 greenhouse gas
Xi Jiang,Daniel Mira,D.L. Cluff +2 more
TL;DR: A review of fugitive methane combustion mitigation and utilisation technologies, which are primarily aimed at methane emissions from coal mining activities, with a focus on modelling and simulation of ultra-lean methane oxidation/combustion is presented in this paper.
Journal ArticleDOI
Parallel mesh partitioning based on space filling curves
TL;DR: This paper presents a fast and scalable geometric partitioner based on Space Filling Curves (SFC), as an alternative to the standard graph partitioning approach, and has avoided any computing or memory bottleneck in the algorithm.

Alya: Towards Exascale for Engineering Simulation Codes
Mariano Vázquez,Guillaume Houzeaux,Seid Koric,Antoni Artigues,Jazmin Aguado-Sierra,Ruth Arís,Daniel Mira,Hadrien Calmet,Fernando M. Cucchietti,Herbert Owen,Ahmed Taha,José María Cela +11 more
TL;DR: This paper presents Alya's performance up to 100.000 cores in Blue Waters, the NCSA supercomputer, and shows scalability plots for all cases, discussing all the aspects of such kind of simulations, including solvers convergence.
Journal ArticleDOI
Turbulent combustion modelling of a confined premixed jet flame including heat loss effects using tabulated chemistry
TL;DR: In this article, the coupling of a flamelet database, to a low-Mach approximation of the Navier-Stokes equations using scalar controlling variables is addressed, which is characterized by the chemistry tabulation based on laminar premixed flamelets in combination with an optimal choice of the reaction progress variable, determined based on the computational singular perturbation (CSP) method.
