2.4.1. System Commands for LINUX-based Operating Systems

If you are running ANSYS Fluent Meshing on a LINUX operating system, all characters following the !

up to the next newline character will be executed in a subshell. Any further input related to these system

commands must be entered in the window in which you started the program, and any screen output

will also appear in that window.

If you start ANSYS Fluent Meshing remotely, this input and output will be in the window in which you

start Cortex.

> !rm junk.*

> !vi script.rp

The ls and pwd aliases invoke the LINUX ls and pwd commands in the working directory. The cd

alias changes the current working directory of the program. The !ls and !pwd commands will execute

the LINUX commands in the directory in which Cortex was started. The screen output will appear in

the window in which you started ANSYS Fluent Meshing, unless you started it remotely, in which case

the output will appear in the window in which you started Cortex.

Note

The command !cd executes in a subshell, so it will not change the working directory either

for ANSYS Fluent Meshing or for Cortex, and it is therefore not useful.

Typing cd with no arguments will move you to your home directory in the console. Examples of system

commands entered in the console are as follows:

> !pwd

> !ls valve.*

Example output (in the window in which ANSYS Fluent Meshing–or Cortex, if you started the program

remotely–was started):

/home/cfd/run/valve

valve1.cas valve1.msh valve2.cas valve2.msh

2.4.2. System Commands for Windows-based Operating Systems

If you are running ANSYS Fluent Meshing on a Windows operating system, all characters following the

! up to the next newline character will be executed. The results of a command will appear in the ANSYS

Fluent Meshing console, or in a separate window if the command starts an external program, such as

Notepad.

> !del junk.*

> !notepad script.rp

!cd and !dir execute the DOS commands and the screen output appears in the ANSYS Fluent

Meshing console. The !cd command with no argument displays the current working directory in the

ANSYS Fluent Meshing console.

Example input and output (in the ANSYS Fluent Meshing console):

> !cd

p:/cfd/run/valve

2.5.Text Menu Input from Character Strings

When writing a Scheme extension function for ANSYS Fluent Meshing, it is convenient to be able to

include menu commands in the function. This can be done with ti-menu-load-string. For example,

to open graphics window 2, use:

(ti-menu-load-string "di ow 2")

A Scheme loop that will open windows 1 and 2 and display the front view of the grid in window 1 and

the back view in window 2 is given by

(for-each

(lambda (window view)

(ti-menu-load-string (format #f "di ow ~a gr view rv ~a"

window view)))

’(1 2)

’(front back))

This loop makes use of the format function to construct the string used by menu-load-string.

This simple loop can also be written without using menu commands, but you need to know the Scheme

functions that get executed by the menu commands to do it:

(for-each

(lambda (window view)

(cx-open-window window)

(display-grid)

(cx-restore-view view))

’(1 2) ’(front back))

String input can also provide an easy way to create aliases within ANSYS Fluent Meshing. For example,

to create an alias that will display the grid, you can type the following:

(alias ’dg (lambda () (ti-menu-load-string "/di gr")))

Then any time you enter dg from anywhere in the menu hierarchy, the grid will be drawn in the active

window.

Important

ti-menu-load-string evaluates the string argument in the top level menu. It ignores

any menu you may be in when you invoke ti-menu-loadstring. Therefore, the command

(ti-menu-load-string "open-window 2 gr") ; incorrect usage

will not work even if you type it from within the display/ menu. The string itself must

cause control to enter the display/ menu, as in

(ti-menu-load-string "display open-window 2 grid")

of ANSYS, Inc. and its subsidiaries and affiliates.

Text Menu Input from Character Strings

create-bounding-box

creates the bounding box for the specified zones.You can specify the zone type, name, edge length, and

the extents of the box, as required.You can also optionally create a geometry object from the bounding

box created.

create-cylinder

creates a cylinder by specifying the axis, radius, and edge length or three arc nodes, the axial delta, the

radial gap, and the edge length.You can also specify the prefix for the zone being created, as required.

You can also optionally create a geometry object from the cylinder created.

create-plane-surface

creates a plane surface by specifying either the axis direction, axial location, and the extents of the surface

or three points defining the plane.You can also optionally create a geometry object from the plane surface

created.

create-revolved-surface

creates a revolved surface by rotating the specified edge through the angle specified. Specify the number

of segments, scale factor, and the pivot point and axis of rotation.You can also optionally create a geometry

object from the revolved surface created.

create-swept-surface

creates a surface by sweeping the specified edge in the direction specified.You need to specify the distance

to sweep through and the number of offsets, as required.You can also optionally create a geometry object

from the swept surface created.

delete-all-dup-faces

searches for faces on all boundary zones that have the same nodes and deletes the duplicates.

delete-duplicate-faces

searches for faces on a specified zone that have the same nodes and deletes the duplicates.

Duplicate faces may be present if you generated the boundary mesh using a third-party grid gener-

ator, or if you have used the slit-boundary-face command to modify the boundary mesh

and then merged the nodes.

delete-free-edge-faces

enables you to remove faces with the specified number of free edges from the specified boundary zones.

delete-island-faces

enables you to delete faces in a non-contiguous region of a face zone.

delete-unconnected-faces

enables you to delete the unconnected face-zones.

delete-unused-faces

deletes all the boundary faces that are not used by any cell.

delete-unused-nodes

deletes the boundary nodes that are not used by any boundary faces.

edge-limits

prints the length of the shortest and longest edges on the boundary.This information is useful for setting

initial mesh parameters and refinement controls.
