The article presents the results of numerical modeling of the distribution of snow on a hyperbolic paraboloid with straight edges. Numerical simulation based on the Euler-Euler method in multiphase flow theory uses a mixture model using commercial CFD software FLUENT ANSYS. The result is presented in the form of a counter map of the snow load shape coefficients at different wind speeds and directions and geometric parameters of the hypar roof; the most unfavorable form of snow distribution is shown. The simulation results showed that the weight of the snow cover on the surface at α = 0° little depends on changes in the geometrical configuration of the hypar, but in general it decreases with an increase in the rise of the shell. At the same time, at α = −45° or α = +45°, the rise of the shell significantly affects the final total weight of the snow cover. At α = −45° the weight of the snow cover increases with the rise of the hypar. The total weight of snow on the surface at α = +45° about 8 times less than at α = −45° or α = 0° ... At α = 0° the degree of asymmetry in the distribution of snow masses on coatings for all forms increases with the rise of the shell rise, while at α = +45° the degree of asymmetry decreases as the hypar rises.
