|Type of mesh
The translator creates an AIRFLO3D input file in ASCII or binary format
using the following files:
unstructured domain file
boundary condition file
airflo3d initialization file (airflow3d_data)
The AIRFLO3D initialization file is located in the directory $ICEM_ACN/icemcfd/output-interfaces.
The user can keep his own initialization file for each configuration in
the project directory. This file should be named "airflow3d_data".
To call the translator, use the following menu entries:
output menu; select solver > AIRFLO3D
output menu; write input
Specify options for the AIRFLO3D interface:
ASCII or binary
name of boco file
name of airflo3d file
Edit the initialization file, if necessary.
The translator creates the airflo3d file in the project directory. ASCII
files have the extension .dat, binary files have the extension .bin.
Defining boundary conditions for AIRFLO3D
From the menu "Output", click on the icon "Boundary Conditions". A window
opens allowing to define boundary conditions for Airflo3d.
Please refer to the General
section for more details.
1. Boundary conditions related
To specify the initial velocity values for a domain, set the following
variables in the boundary conditions menu:
- Enter the X-component of the velocity.
- Enter the Y-component of the velocity.
- Enter the Z-component of the velocity.
If undefined, the default initial velocity
values from the airflo3d initialization file are assigned to it.
2. Boundary conditions related to subfaces:
There are 4 valid boundary condition definitions for subfaces in AIRFLO3D.
For each subface exactly one of the following boundary condition definitions
- Static Wall: Np, Tw
- Moving Wall: Np, Tw
- Velocity Inlet: Np, Vx, Vy, Vz
- Velocity Outlet: Np, Vx, Vy, Vz
- Symetry Plane: Np
where Np is the plane number, Tw is the wall temperature and Vx, Vy and Vz are the three components of the velocity.
