The physical parameters of the simulated shear-layer are
The initial field is a solution of the Blasius equation. The inflow is forced using eigenfunction of the viscous linear stability theory.
Computational results with DGSEM code STRUKTI using 424x144x2 grid cells and an N=5 Gauss node approximation resulting in 26,376,192 degrees of freedom and approx. 60,000 time steps. The wall clock time was about 8 hours using 636 Nehalem cores at the computing center in Stuttgart (HLRS)
