ANSYS ICEM CFD - Unigraphics Interface

PLOT3D Interface

Solver	Plot3d
Type of mesh	multiblock mesh
Dimension	2D and 3D

(Return)

The translator creates an "xyz" file in the PLOT3D file format. This file contains the grid information and optionally the IBLANK array.

Creating the PLOT3D Input File

The translator writes the PLOT3D input file using multiblock, the boundary condition file and the topology file. To create the PLOT3D input file, select the translator "PLOT3D" in the "Output" menu. After clicking "Write input" you can specify options for the PLOT3D interface:

select formatted, unformatted or binary output
select data layout in planes or "whole"
select single or double precision
select include or omit IBLANK array
give the name of the extended topology file
give the name of the boundary conditions file
specify a scaling factor (default is 1.0)
give the name of the PLOT3D input file (default is "xyz")

The interface generates the PLOT3D file (xyz) located in the project directory. Formatted files get the extension .fmt, unformatted files get the extension .dat.

Defining boundary condition for PLOT3D (IBLANK array)

To define boundary condition click on the "BC" icon in the "Output" menu. Supported boundary conditions are:

Boundary conditions	Value(s)
IBLANK value	enter any IBLANK value (default 1)

IBLANK values with special meanings are:

0 = off (for whole domains only)
1 = normal
2 = solid wall boundary
-n = space continues on grid n

The IBLANK values 1, 2, and -n are generated by the translator.
