“…In this regard, it is relevant to create a bank of test examples of precisely solvable non-stationary hydrodynamics problems in conditions of complex geometry, the use of which will allow one to verify the calculation results and evaluate their accuracy. Works [13][14][15][16][17][18][19][20][21] present the results of numerical modeling of three-dimensional fluid flows and estimates of their computational accuracy, and works [22][23][24][25][26] present some classes of exact solutions.…”

The work visualizes flows corresponding to the exact solutions of the system of hydrodynamic equations previously published by the authors, consisting of the vector Navier-Stokes equation and the law of conservation of mass for an incompressible fluid. This work uses the MathGL library for the C/C++ language and ParaView for scientific visualization of the results of numerical and analytical calculations. Without the use of such means, it would be impossible to see that the fluid flow is stratified into invariant subregions, and the trajectories of motion of fluid particles are wound on torus-shaped surfaces. Most of the scientific works on the study of hydrodynamic equations cover the results of calculations and do not address the questions of the existence of exact analytical solutions. At the same time, these calculations are performed with a specially selected set of fitting parameters unique to the equipment used and the computer software used. Questions about trust in the results of such calculations, their verification with exact solutions and the creation of a bank of test examples of applied problems in order to certify the applicability of the calculation results in practice become relevant.
