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
|
