High-quality movie of a turbulent boundary layer direct numerical simulation (DNS) and large-eddy simulation (LES) performed in 2010, reaching up to Re_theta=4300. Simulations were performed with up to 7.5 billion grid points on the Ekman cluster at KTH Stockholm. More information and simulation data: http://www.mech.kth.se/~pschlatt/DATA. Movie with better resolution: http://arxiv.org/abs/1010.4000\r\n\r\nResults of this DNS are described in Schlatter and Orlu, 2010, Journal of Fluid Mechanics, 659, 116-126.\r\n\r\nThe simulations use a spectral discretisation of the incompressible Navier-Stokes equations on a grid with up to 8192x513x768 spectral modes.\r\n\r\nSimulation code: Simson (http://www.mech.kth.se/~mattias/simson-user-guide-v4.0.pdf)\r\n\r\nhttp://www.mech.kth.se/mech/info_staff.jsp?ID=216
