The paper describes an automatic generator of unstructured quadrilateral surface grids for geometric models in the parametric representation. The grid generator is intended to construct grid models for strength simulations in the "Logos" software package. Steps of the surface grid generation procedure are considered. One of the steps, namely generation of quadrilateral grids in the parametric plane, is discussed in detail. Examples of test problems with different geometric models are given.Keywords: "Logos" software package, quadrilateral surface grids, moving front, generation of quadrilateral cells, local smoothing, topological optimization.
