CHARLES™, Cascade Technologies flagship product, is a high-fidelity unstructured compressible flow solver for Large Eddy Simulation (LES), ideally suited for aeroacoustic applications involving high-speed flows and complex geometries. The numerical schemes embedded in CHARLES provide a high-fidelity representation of turbulent fluctuations without introducing any artificial damping, i.e. numerical dissipation. Substantial effort is devoted to the efficiency of the algorithms and their applicability to large scale parallel computations (on the order of 150,000+ cores).  All the physical models in CHARLES were modified and enhanced to take advantage of the wealth of information provided by the direct representation of large scale turbulent motions. …………………………………………………………….. ……………………………………………………………………………..
