NUMECA's Flow Solver (EURANUS) General Technical Specifications

  • 3D Reynolds-averages Navier-Stokes Solver
  • Multi-block embedded grids
The code has a structured multiblock approach for handling complex geometries. In addition, it supports non-continuous grid lines through block connections, allowing a large flexibility in multi-block mesh definition. It provides a natural mechanism for parallelization by assigning different blocks to different processors
  • Full second order spacial discretization
- Numeca's Flow Solver contains a variety of numerical schemes :
Central schemes and upwind high resolution schemes
  • Time integration : Explicit Runge-Kutta schemes
  • Highly efficient multigrid convergence acceleration :
Mach number range from very low speed (incompressible) to transonic/supersonic/hypersonic regime
  • Steady or unsteady flows
  • Heat transfer and buoyancy
  • Highly efficient multigrid convergence acceleration
  • Full 3D, 2D and axi-symmetric simulations
  • Multisatge throughflow capability
  • Incompressible, subsonic and transonic/supersonic flows
  • Advanced and robust turbulence models :
Baldwin-Lomax k-e with wall functions Low Reynolds k-e model :

  • Real or perfect fluids
  • Chemical capabilities & Real gas based on multi species models with or without chemical reactions

  • Condensable gas defined through thermodynamic tables or polynomial equations
  • Flow particule interaction in lagrangian mode
  • Multi-phase flows
  • Porous media
  • Non newtonian fluids
  • Parallel multi-processor calculations
