Abstract

A supercomputer simulation of the benchmark MATiS-H problem is considered. A highresolution CABARET code is applied for solving Navier-Stokes equations in the framework of the Monotonically Integrated LES approach for the MATiS-H problem. The code is based on a generalisation of low-dissipative, low-dispersive and non-oscillatory CABARET scheme to hybrid topology meshes in the supercomputing framework. The solutions for the time-averaged fields are reported. These show a relatively small sensitivity to the grid density. Comparison with the experiment data available is provided.
