On the influence of a spatial mesh structure on the results of numerical simulation of a shock wave in a flow around a 3D model. (English) Zbl 1509.76060
Summary: The influence of the structure of a 3D spatial mesh on the quality of numerical modeling of viscous compressible gas flow at a Mach number equal to 3 around a forward-facing part of a rectangular cylinder is demonstrated. The results obtained show that the mesh structure critically affects the shape and the intensity of the head shock wave, and its influence can exceed that of other mesh-related effects. The calculations are performed using a finite volume method implemented for regularized or quasi-gas dynamic equations.
