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

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
*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

CUSTOMIZED MULTIWINDOW DISPLAY
OF COMPUTED DATA
- DIRECT OUTPUT OF LIFT, DRAG & MOMENTS.
*IGG and CFView are
products from NUMECA International |
