The HEXPRESSTM / Hybrid program appeared on the market as a response to the need of European automotive companies in a fast and efficient mesh (grid-builder), with which it is possible to build computational grids for the most complicated topologies in extremely short time. At the moment, this, in our opinion, is the only known tool that allows building a grid for calculating both the external and internal aerodynamics of a complex object such as a car, including the engine compartment and interior interior, in one day, starting directly from the "unclean" geometry .

HEXPRESSTM / Hybrid offers its own technology of meshing and its original approach to the construction of nets. Preprocessing is divided into two stages, the first is the work with geometry in the user interface of the program. The second stage is the launch of the grid construction from the command line (in the style of working with Linux, Unix operating systems) using a text configuration file that specifies the meshing parameters. The parameters of the meshing are few, they are intuitive. The main advantage of combining the GUI philosophy and working in the command line with the use of the configuration file is the speed and automatism in rebuilding the grids, the process of building new grids for new standard geometries is accelerated many times, bypassing, often, the tedious stage of grid configuration in the user interface (you already have there is a ready config file and all that is needed, just start the process of building the grid).

The process of constructing grids in HEXPRESSTM / Hybrid is completely parallelized, by default it runs on all available parallel processor cores of the computer.

Unique innovative technologies incorporated in HEXPRESSTM / Hybrid allow for the automatic construction of hexadominant, conformal meshes (it is possible to build tetra or fully hexadecks) for the entire settlement domain or several domains, the grid is constructed with the resolution of the wall layer or without it, if desired.

A key feature of HEXPRESSTM / Hybrid is that it is not exacting to the purity of the initial geometry and can build a mesh for geometries with serious flaws, slots, etc., which in general reduces the time of the grid construction by working order when working with real, "unclean" geometries .

HEXPRESSTM / Hybrid has a built-in tool for automatic search and hole-sealing, which allows you to start working with almost any geometry that you were given, without the knowledge or time to solve the problem in CAD or similar systems.

HEXPRESSTM / Hybrid is an ideal tool for building large-scale grids, the most complex topology of geometries in the shortest possible time.

At the moment, HEXPRESSTM / Hybrid has found its fans in almost all branches of engineering and industry, including such atypical areas as medicine.
