Nokka, Marjaana (University of Jyväskylä, 2016)The papers included in the thesis are focused on functional type a posteriori error estimates for the Stokes problem, the Stokes problem with friction type boundary conditions, the Oseen problem, and the anti-plane Bingham ...
Designing a graphics processing unit accelerated petaflop capable lattice Boltzmann solver: Read aligned data layouts and asynchronous communication Robertsén, Fredrik; Westerholm, Jan; Mattila, Keijo (Sage, 2017)The lattice Boltzmann method is a well-established numerical approach for complex fluid flow simulations. Recently, general-purpose graphics processing units (GPUs) have become available as high-performance computing ...
Hegele, L. A.; Scagliarini, A.; Sbragaglia, M.; Mattila, Keijo; Philippi, P. C.; Puleri, D. F.; Gounley, J.; Randles, A. (American Physical Society, 2018)We present a boundary condition scheme for the lattice Boltzmann method that has significantly improved stability for modeling turbulent flows while maintaining excellent parallel scalability. Simulations of a ...
Makkonen, Pekka (2016)This work describes the deployment of the current fluid flow simulation software, Star-CCM+, at Valtra Inc. The text also gives a brief introduction to computational fluid dynamics and its role in the product development ...
