MESH
|
|
EURANUS/AERO has a structured
multiblock
approach for handling complex geometries.
In addition the code supports non-continuous
grid lines through block
connections, allowing a large flexibility in multiblock mesh definition.
Provides a natural mechanism for parallelization
by assigning different blocks to different processors.
- SPATIAL DISCRETIZATION
EURANUS/AERO contains a variety of numerical
schemes:
- Central schemes
- Upwind high resolution schemes
- Explicit Runge-Kutta schemes
- Implicit relaxation schemes
-
MULTIGRID CONVERGENCE ACCELERATION
- MACH NUMBER RANGE FROM
VERY
LOW SPEED TO TRANSONIC / SUPER
/ HYPERSONIC REGIME
-
TURBULENCE MODELS
Algebraic and various transport equation models
are available, with
or without wall functions

|
- REAL OR PERFECT FLUIDS
- CHEMICAL CAPABILITIES
EURANUS/AERO is handling multi species with or without chemical reactions
- STEADY OR UNSTEADY FLOWS
- FULL 3D, TWO-DIMENSIONAL AND AXISYMMETRIC SIMULATIONS
| Fields
of Applications
EURANUS/TURBO can simulate any compressible
or incompressible flow, with
or without chemical reactions
such as:
- flow around cars, aircraft or ships
- flow around buildings
- species dispersion

- A FULLY INTEGRATED PLATFORM, combining:
- IGG, an Interactive
Geometry Modelling and Grid Generation System, providing the most advanced
and original tools for multiblock 3D structured
grids
- EURANUS/AERO
- CFView, a
Computational Field Visualization System, offering all qualitative and
quantitative flow
analysis tools through a highly interactive object-oriented
interface
- Transparent data transfer.
An internal system
is taking care of the file
transfer between the processes.
No file editing or user intervention is necessary
|
Before launching the code on the finer
grid, the user can run a simulation on any possible
lower grid levels without any grid manipulation
g.
Through the use of menu items, the
user can control the evolution of the solution,
stop, interrupt or resume the computation
from any previous solution
Easy Navigation through the different
systems. At
any time during the computation, the user
can access IGG or CFView to modify
the grid or check intermediate results,
without interrupting the CFD run
