Pioneering CFD Software for Education & Industry

Modelling Capabilities

• Problem dimensionality: one, two and three dimensions.
• Time dependence: steady state and transient processes.
• Grid systems: Cartesian, cylindrical-polar and curvilinear co-ordinates; rotating co-ordinate systems; multi-block grids and fine grid embedding.
• Compressible/incompressible flows.
• Newtonian/non-Newtonian flows.
• Subsonic, transonic and supersonic flows.
• Flow in porous media, with direction-dependent resistances.
• Convection, conduction and radiation; conjugate heat transfer, with a library of solid materials and automatic linkage at the solid fluid interface.
• A wide range of built-in turbulence models for high and low-Reynolds number flows; LVEL model for turbulence in congested domains and a variety of K-E models, including RNG, two- scale and two-layer models.
• Multi-phase flows of three kinds with a variety of built-in interphase-transfer models:
  1. Inter-penetrating continua, including turbulence and modulation;
  2. Particle tracking, including turbulence dispersion effects;
  3. Free-surface flows.
• Finite-volume approach on staggered or collocated grids, with 13 choices of discretisation schemes for convection.
• Combustion and Nox models, with a range of diffusion and kinetically controlled models including the unique Multi-Fluid Model for turbulent chemical reaction.
• Chemical kinetics including multi-component diffusion and variable properties. Built-in interface to the CHEMKIN chemical database.
• Advanced radiation models, including surface-surface model with calculated view factors, a six-flux model and composite radiosity model for radiative heat transfer, known as IMMERSOL
• Mechanical and thermal stresses in immersed solids can be computed at the same time as the fluid flow and heat transfer.
