Program FINE / Open ( old name Fine / Hexa) – calculated CAE software package for solving general-purpose CFD problems in hydrodynamics , gas dynamics , aerodynamics ( simulation of complex internal and external flows ) . Complex structure FINE / Open: HEXPRESS: automatic mesh generator for hexahedral mesh generation ; HEXPRESS / Hybrid: newest advanced generator geksadominantnyh nets ; HEXSTREAM: 3D Reynolds equations solver ; CFView: renderer and analysis solutions ; OpenLabs: module for adding your own models; FINE GUI: interactive graphical user interface . The main advantages of FINE / Open: automatic generation of structured and unstructured meshes of high quality; wide range of physical models and turbulence models ; rapid convergence of the solution due to the original multigrid scheme; use of technology adaptation ( grinding / enlargement ) grids in the solution process ; high quality results through sustainable sampling schemes of high accuracy ; quick and easy visualization solutions . HEXPRESS – a unique innovative mesh generator that automatically creates high-quality hexahedral meshes for complex geometric objects : the fuselage , suspension , chassis , internal and external geometry of aircraft engines, internal passages cooled turbine blades, air intakes , etc. . Using this tool reduces preparation time to the calculation problem and simplifies the work of engineer by automatically constructing high-quality hexahedral meshes with viscous boundary layer explicit permission . Main advantages: possibility of direct import CAD geometry ; eliminates the need for constructing the grid surface by allowing the grid to finish building automatically from the surface of the volume ; function wizard: quick and simple meshing ; automatic mesh refinement based on user settings , or by setting the condensation region ; batch mode ; powerful optimization algorithm , smoothing grids. OpenLabs – powerful module that extends the standard capabilities of FINE / Open. OpenLabs to add new physical models and modify existing user desires. This does not require programming skills , saving considerable time . With OpenLabs you can : modify or add to the model constants enhance the transport equation ( convection, diffusion , sources) make changes to the initial solution , the boundary conditions make the source term in the transport equation change in the diffusion coefficients of the transport equation to solve conservative or conservative , user-defined transport equation. Areas of application: PC FINE / Open is used to solve a wide range of practical problems in fluid dynamics modeling chislennog the field of aviation , aerospace, turbomachinery , medical , automotive, civil engineering , etc.
