The description of the automatic generator of unstructured tetrahedral isotropic grids with prismatic layers is given. The generator is used to construct grid models when solving the aero- and hydrodynamics problems with the LOGOS software package. The stages of generating a volume grid are considered. The specific features of the arbitrarily-shaped model geometry are taken into account in the grid generation. Keywords: LOGOS software package, preprocessor, unstructured grids, prismatic layer, Delaunay triangulation with limitations, moving front.
