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.

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.

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.

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.

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.
