The paper presents two methods to improve the efficiency of supersonic flow simulation using arbitrarily shaped unstructured grids. The first method promotes increasing the numerical solution convergence rate and is based on the geometric multigrid method for initialization of the flow field. The method is used to obtain the initial field of distributed physical quantity values. which... https://www.bekindtopets.com/hot-super-Chervo-Marco-Jacke-Herren-limited-grab/
