BU's College of Engineering, Center for Computational Science (CCS), and Information Systems & Technology (IS&T) announce a significant expansion to the facilities for research computing with the acquisition of a GPU-accelerated cluster. At 80 teraflop/s in peak double-precision performance, this system will be the fastest ever deployed at BU. The new computing resource was made possible by... Continue »
FMM-based vortex method for simulation of isotropic turbulence on GPUs, compared with a spectral method, Rio Yokota, L. A. Barba, Computers & Fluids, in press (available online 13 August 2012), doi:10.1016/j.compfluid.2012.08.002 This paper presents the results of comparing a Lagrangian vortex method with a trusted spectral method for the simulation of isotropic fluid turbulence. The numerical engine of the vorticity-based fluid... Continue »
We have developed a Navier-Stokes solver, called cuIBM, to simulate incompressible flows using immersed boundary methods. This document provides background on the numerical methods implemented in the cuIBM code framework and evidence of the validation exercise carried out by the authors. The code provides... Continue »
