FlowVision multi-purpose CFD system

Unique FlowVision HPC Rev. 3.0 capabilities

Automated and unique grid generation

• Unique grid generation concept and technical implementation – operates directly on CAD geometry
• Ease of use and efficiency – for most complex geometry (e.g. medical applications – non structured geometry
• CAD fitted grid – describes exact all geometric features and boundaries (Sub-Grid Resolution)
• Grid generation time – minutes vs. days or weeks
• Direct coupling between fluid grid and FEM mesh

Automatic grid adaptation

• Adaptation to geometry                                                 
• Adaptation to solution

Moving bodies (multiple) in simulation domain
Hybrid modeling

• Unique “Clearance Model” – for efficient modeling of small clearances (compressors, bearings, etc.)
• Automatic recognition of clearance cells to apply different calculation model
• Optimized and verified clearance model

Multi-phase

Efficient tracking of free surface (VOF)

Fluid Structure Interaction  (direct coupling with Abaqus)

• Direct coupling with Abaqus
• MPM (Multi Physics Manager) for automatic and optimal data exchange control

C++ implementation

Modular architecture (distributed client server implementation)

• Easy to add specialized modules and new functions
• Client Windows
• Server Linux/Windows

Easy extendable solver (special models, equations, formulas)

Visualization of results in parallel with simulation
 
Parallel solver (Linux clusters, multiple processor computers)

• Optimized performance (mostly linear dependence from number of processors)

Updating or changing geometry at any moment of simulation  (open for automated optimization)

• New (modified) geometry can be submerged into computational space at any moment of simulation
• Open for automatic optimization
