After verifying the prerequisites, the setup process will install
OFFROAD2007
.
As with
most software installations, you can verify the destination folder and control installation
of Start Menu and Desktop links.


GETTIN
G STARTED


By default, the software installs in a folder under the Windows default program location:


C:
\
Program Files
\
OFFROAD2007


In this location you will find three subfolders:



Bin
--

Program binaries (.exe and .dll files) and configuration files.


D
ata


Data files required to run cases.


Run


User input and output files.


You can start the program from the Start/Programs/
OFFROAD2007

menu, from the
OFFROAD2007

link on the desktop, or by opening the
Offroad.Launcher.exe

program in
the “Bin” folder.


OFFROAD2007

uses a front
-
end/back
-
end architecture. The front end
“GUI”

allows you
to open, edit, save, and run input files. The back end
“model”
runs the input files and
generates report files. Generally, all user interaction is with the
GUI.


The
GUI is

al
ways in one of two states, either

editing

input files
or
running

input files.
When the program first starts, you can immediately begin editing a new input file. Use
the File menu to open an existing input file to modify.


While

editing input, click on
any of the tabs across the top (Episode, Reporting, Area,
Fuel and HP, or Data Files) to select a category of input parameters.


When you have finished with an input file and saved it, you can use the Run menu to
start the back end
model. Whi
le the
model

is running a case, you can review the inputs
using the GUI
but you will not be able to modify them.


OUTPUT FILES


After a case has been run, the output (report) files are located in the Run folder. Look at
file

Messages.out


for warnings, error messages,

and a complete echo of all input
settings.


Each
output file (report) generated
contains a single “table.” The files all begin with a
header that names all the columns, followed by rows of tab
-
delimited data.
