GridTool: A Tool for Structured and Unstructured Grid Generation
GridTool Executions
GridTool can be executed by typing "GridTool" or "GridTool options
filename", and here is a list of
command line argument,
Command Line Arguments
Arguments Action
-h help
-d3m d3m_filename read a d3m file
-dat dat_filename read a dat file
-f restart_filename read a restart file
-gf gridgen_filename read a gridgen formatted file
-g gridgen_filename read a gridgen binary file
-pf plot3d_filename read a plot3d formatted file
-p plot3d_filename read a plot3d binary file
-IGES IGES_filename read an IGES file
-felisa run GridTool in FELISA Mode
When GridTool starts, it looks for the resource file, ".GridTool". This
file could be at either the user's root, the current directory or
defined by "setenv" unix command as "setenv GridTool_resources
my_resource_filename". Users may change the resource file by
customizing it to their needs. If the resource file does not exist,
GridTool will use the defaults values which are listed in the
Sample Resource File section .
The resource file may
contain the preferred colors for displaying objects and the boundary
conditions. A comment line can start either with a space or "#" in the
first column. The default boundary conditions are based on the
USM3D [11] code developed by
Dr. Neal Frink at
NASA/Langley Research Center. In the following sections, the
application of GridTool for setting up data files for an advancing
front technique (VGRID system) is described. One important feature of
GridTool is that each operation is accomplished in one step only.
Therefore users can create and manipulate objects randomly.
There is some limited on-line help which can be activated by pressing
the "Help" button in the main panel which in turn will open a
browser. As the user moves the cursor over any object in the panels, a
description of that button will be given in the browser.
