New exaFMM paper accepted

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 »
