The high order of accuracy, combined to geometric flexibility and parallel scalability of DGM, provide - on paper - an ideal method for this type of simulation. Irrespective of whether this type of simulation is required for building design today, it is interesting to see already now how the DGM, compares to state of the art commercial solvers, as unsteady scale-resolving approaches will pervasive in the future. DGM computations on the ADNBATI benchmark are compared to DNS and URANS simulations performed by a state of the art commercial solver. Pages: 3753 - 3760 Paper:
