Description:
GRASP8W-SE (GRASP8W Student Edition) is a software package for analysing
single or double reflector antenna systems. It provides a module, GRASP8-SE,
for performing the electromagnetic computations and a graphical interface in
the form of a pre-processor. The pre-processor assists the user in setting
up the geometry of the problem to be analysed and provides a means for
visualising the system. Also, the pre-processor contains simple plotting
facilities for calculated patterns.
The GRASP8W-SE/GRASP8-SE tools have limited functionality compared to the
professional GRASP8W/GRASP8 tools available through TICRA. As an example,
the Student Edition is restricted to analyse a maximum of two electromagnetic
scatterers, and only a limited number of feed models are available. Apart
from the limited functionality the software follows the same high standard
and computes with the same accuracy as the professional version.
Copyright:
The software is copyright (c) TICRA and protected pursuant to Danish Law as
well as International Law.
Terms of Use:
GRASP8W-SE is a FREEWARE product that neither requires licensing nor

package. Also, the software may not be decompiled, disassembled,
reverse-engineered, or otherwise reduced to a humanly perceptible form in an

Support:
No support is provided with the freeware version.
Computer Configuration:
Win9x/2000/NT, Linux
Distributed Package:
For Win9x/2000/NT :
The software package is distributed as a zip file "g8se.zip" containing
an install program, "setup.exe", which is used to install the files
needed for GRASP8W-SE.
The install program prompts for the destination folder and the user
decides if an entry in the start-menu should be created.
The GRASP8W-SE program is started via the entry in the start-menu or
by double-clicking on the file "grasp8w-se.exe" in the destination
folder. The use of the program is explained in the on-line help
(press "F1" and choose "Getting Started") as well as in the documentation
located in the "documents" subdirectory of the destination folder. The
program is distributed with a number of test-cases located in the
"test_cases" subdirectory of the destination folder.
For Linux :
The software package is distributed as a compressed tar-file
"grasp8w-se.tar.gz", which should be unpacked to a suitable
directory. The software has been developed under the
RedHat Linux environment but should be compatible with other versions
of Linux. It uses X-windows and Open Motif 2.1 (downloadable
from http://www.opengroup.org/openmotif).
Documentation:
Included in the distributed package are three files used for the
documentation of the program.
GRASP8W-SE.HLP contains a help facility for the pre-processor with
information about how to a) create antenna geometries, b) define
analysis objects, and c) set up commands for calculating the performance
of the antenna system.
GR8SUM.PDF contains the GRASP8 Manual, which describes the general reflector
and antenna farm analysis program GRASP8. An overview of the capabilities is
given in the manual, together with some examples of input and field
calculations. The manual also contains a reference section describing
in detail the available user input to the program.
TECHDES.PDF contains the GRASP8 Technical Description. This document describes
a) the mathematic and electromagnetic models used in the program to set up
antenna systems, b) the analysis methods used to calculate the performance
of the antenna system, c) the file formats used in the program, and d) a
number of applicational examples.
The Help file is specially tailored to the GRASP8 Student Edition whereas the
Manual and the Technical Description are the same documents as for the
professional GRASP8 software.
The Help file can be accessed from the pre-processor using the F1-button. The
Manual and the Technical Description are supplied as pdf-files which may be
viewed using the Acrobat Reader by Adobe
(downloadable from http://www.adobe.com/acrobat).
