Flow Vision, CFD multi-purpose simulation

FlowVision CFD system

FlowVision is a new generation multi-purpose simulation system for solving practical CFD (computational fluid dynamics) problems. The modern C++ implementation offers modularity and flexibility allowing addressing the most complex CFD areas. Unique approach to grid generation (geometry fitted sub-grid resolution) provides natural link with CAD geometry and FE mesh. The Abaqus integration through Multi-Physics (MP) Manager supports the most complex fluid-structure interaction (FSI) simulations (e.g., hydroplaning of automotive tire). FlowVision integrates 3D partial differential equations (PDE) describing different flows, viz., the mass, momentum (Navier-Stokes), and energy conservation equations. The system of the governing equations is completed by state equations. If the flow is coupled with physical-chemical processes like turbulence, free surface evolution, combustion, etc., the corresponding PDEs are added to the basic equations. All together the PDEs, state equations, and closure correlations (e. g., wall functions) constitute the mathematical model of the flow. FlowVision is based on the finite-volume approach to discretization of the governing equations. Implicit velocity-pressure split algorithm is used for integration of the Navier-Stokes equations. FlowVision is integrated CFD software: its pre-processor, solver, and post-processor are combined into one system. A user sets the flow model(s), physical and method parameters, initial and boundary conditions, etc. (pre-processor), performs and controls calculations (solver), and visualizes the results (post-processor) in the same window. Any time he can stop calculations, change the required parameters, and continue or recommence the calculations. Capvidia/ТЕСИС develops two versions of the software: sequential FlowVision 2.xx.xx and parallel FlowVision 3.xx.xx (or FlowVision-HPC). Both systems employ modern technologies of CFD and computer graphics. Source: http://www.fv-tech.com/content/view/125/72/lang,russian/
