Towards DNS of a compressible round-jet at Reynolds number 23,000

The plot below shows h-convergence results of our DG code Strukti for a compressible turbulent round-jet, using polynomials with degree N=5. Increasing the total DOF per equation from 21 mill. up to 170 mill. DOF shows that the range of scales of the DG solution still changes and thus shows that the approximation is not converged yet…
