ATM Truss analysis software - free

["Tom Krajci" <tkrajci@san.osd.mil>]

I have downloaded an evaluation copy of some free truss analysis
software.  

http://www.grapesoftware.mb.ca/ 

=========From the help file============================
GRAPE SOFTWARE  (Graphic Real-Time Analysis Programs for Engineering).
GBW32 V4.0 is a Finite Element Analysis program that uses standard 3D
beam and truss elements to analyze a wide range of mechanical and civil
structures. GBW32 V4.0 has many special features such as release nodes,
auto and batch analysis, a full feature set of load conditions, DXF
readability and powerful model building characteristics that make it a
very competitive commercial quality program.
=========From the help file============================

The help file has an example to lead you by the hand to set up a 2D and
a 3D truss.  After that it's pretty easy to make telescope truss
structures to analyze and compare various design ideas.

You can view an animation of the truss deflecting to whatever loads you
define.  Other analysis methods show you the stress/strain in various
truss elements.

With this software I find it easy to compare 6 or 8 truss structures,
and now I can compare X-brace and Quad-Tripod arrangements too!

What truss analysis software do other ATM's use?

I hope this helps,
