The paper describes a capability of building dual meshes in parallel mode, which has been implemented in the mesh generator of the "Logos Hydrogeology" digital product. A dual mesh of polyhedral cells is considered, such mesh is built on the base of the primary mesh, which cells are tetrahedrons, prisms, hexahedrons, and pyramids. The program conception is considered and the mesh generator algorithm of building dual meshes is described. The specific features of the mesh generator operation in the parallel mode of generating mesh models and possible cases of the dual mesh generation method limitation are emphasized. Resultant mesh models are demonstrated by examples of the test and real-world models of territories. Results of building mesh models both in the parallel and serial modes are given. Keywords: "Logos Hydrogeology", subsurface hydrodynamics, unstructured mesh, dual mesh, polyhedrons.
