Development of a central-moment phase-field lattice Boltzmann model for thermocapillary flows: Droplet capture and computational performance
Markus Holzer, Travis Mitchell, Christopher R. Leonardi +1
This study develops a computationally efficient phase-field lattice Boltzmann model with the capability to simulate thermocapillary flows. The model was implemented into the open-s…
Generalized Golub-Kahan bidiagonalization for nonsymmetric saddle point systems
Andrei Dumitrasc, Carola Kruse, Ulrich Ruede
The generalized Golub-Kahan bidiagonalization has been used to solve saddle-point systems where the leading block is symmetric and positive definite. We extend this iterative metho…
Scalable Flow Simulations with the Lattice Boltzmann Method
Markus Holzer, Jayesh Badwaik, Radim Vavrik +7
The primary goal of the EuroHPC JU project SCALABLE is to develop an industrial Lattice Boltzmann Method (LBM)-based computational fluid dynamics (CFD) solver capable of exploiting…
Parallel solution of saddle point systems with nested iterative solvers based on the Golub-Kahan Bidiagonalization
Carola Kruse, Masha Sosonkina, Mario Arioli +2
We present a scalability study of Golub-Kahan bidiagonalization for the parallel iterative solution of symmetric indefinite linear systems with a 2x2 block structure. The algorithm…
A Scala Prototype to Generate Multigrid Solver Implementations for Different Problems and Target Multi-Core Platforms
Harald Koestler, Christian Schmitt, Sebastian Kuckuk +3
Many problems in computational science and engineering involve partial differential equations and thus require the numerical solution of large, sparse (non)linear systems of equati…
