Technique for Creating a Rational Calculation Grid in Calculations Based on the Finite Volume Method

— The issues of the formation of computational meshes for conducting calculations using finite-volume methodologies for solving Navier–Stokes equations are considered. The peculiarities of the creation of a rational unstructured mesh for an aircraft of complicated configuration are revealed. It is shown that the use of the technique developed allows obtaining aerodynamic coefficients of the plane model close to experimental values.
