The paper describes an automatic generator of unstructured grids used to solve problems of aero- and hydromechanics implemented in LOGOS software complex. Stages of generating a 3D grid are considered, an example of the stage-by-stage construction of a grid is given.

Keywords: LOGOS software complex, preprocessor, unstructured grids, a refined grid, grid quality improvement.
