FINE™ / Open with OpenLabs™

Flow Integrated Environment dedicated to the simulation of complex internal and external flows.



FINE™/Open with OpenLabs™ is a powerful CFD Flow Integrated Environment dedicated to complex internal and external flows. FINE™/Open with OpenLabs™ solves any flow, from incompressible to low and high speed flows. It combines completely unstructured hexahedral grids with an efficient preconditioned compressible solver with fast agglomerated multigrid acceleration and adaptation techniques.

FINE™/Open with OpenLabs™ allows users to freely develop and exchange physical models in CFD, with a new open approach to CFD. Complex programming tasks are avoided through the usage of an easy meta-language.

FINE™/Open with OpenLabs™ allows users to develop, improve and customize physical and numerical models as for instance:

  • Transport equations (convection-diffusion-source)
  • Steady or unsteady source terms (heat, force, mass)
  • Diffusion coefficients
  • Algebraic relations
  • Initial and boundary conditions
  • Turbulence models, combustion models, radiation models
  • atmospheric boundary layer models,
  • actuator disk simulations,
  • soot modeling,


FINE™/Open offers solution adaptive grids.

FINE™/Open with OpenLabs™ covers a large range of applications, such as aircrafts (including appendages), turbomachinery (cooled turbine blades and disk), automotive aerodynamics, environmental flows, etc.



  • Full Hexahedral Grids (no prism, no tetrahedra, no pyramid)
  • Direct CAD import capabilities
  • CAD manipulation and decomposition tools
  • Mesh wizard for rapid solution set-up and easy back and forth operation
  • Buffer cell and boundary layer insertion for high quality cells in boundary layer regions
  • Automatic refinement procedures based on user defined sensors either next to solid walls or at specified area in the domain
  • Multi domain capabilities allowing the treatment of CHT and multi-part geometry models
  • Full non-matching multi-block connection, allowing multi-row turbomachinery meshing

FINE™/Open flow solver:

  • One single code for all types of fluids (incompressible, low-compressible, condensable and fully compressible) and speed (low speed to hypersonic regime)
  • Acceleration with the CPU-Booster™ module provides 3-5 times gain in convergence speed
  • Embedded fluid structure interaction with the Modal and Flutter Analysis module
  • Multigrid convergence acceleration
  • Full Non-Matching Boundaries capability
  • Cavitation
  • Python scripting technology


  • OpenLabs™ allows users to customize or add physical models
  • Flexible and user-friendly Graphical User Interface
  • Users don’t need to care about programming details and code structure
  • OpenLabs can be used in a wide variety of industrial and academic applications
  • Identical computing and memory costs compared to source-coded models
  • Free access to all FINE™/Open community


  • Multi-projects and multi-views graphical user interface
  • Python scripting technology
