Welcome to the IMPACT forum

Hello all,

This ia a forum to discuss the features, usage, & problems with an explicit code called IMPACT. It is java based, so it will run on any OS. It has a Pre & Post Processor, Solver & Graphing tool. See it at \"http://impact.sourceforge.net\"

Incidentally, in exchange for Jonas (a co-author) teaching me how to use the GUI based Pre-Processor, I wrote a tutorial for it. See it here: \"http://impactprogram.wikispaces.com\"

Hope to see more users join us. I did not develop the code, just the tutorial. Please direct all questions to one of the developers.

Hello!

If you are new to FEM and/or want to know how to make models for Impact and how to use the IMPACT program itself, you should definitely visit impactprogram.wikispaces.com , as JMB told above.

I made three videos showing each step, from modeling, preprocessing, calculation to postprocessing.
The first model I made is a simple 2d-model of a rectangular rod with a bore:
impactprogram.wikispaces.com/Video1

More complicated models like 3d-shells and volumetric models will come soon.

Also check out Kumar's great step-by-step HTML tutorial here:

See you,

Hello all
I have just managed to install Impact in my Ubuntu 9.10 machine (AMD64). I had difficulty to run this, then found that I need to install Java3D manually. Now it runs.

I run the example bullet, it is very impressive as the elements really split.

I am now thinking to use this for composite materials. Is it possible if I have material with property orientations. If other users tried this, could you please share a simple problem so I can learn how to model composite materials.

Thank you very much.

Regards
Waluyo

hi Waluyo Adi Siswanto,
Thanks for sharing it dear.
it is very much useful information
what are the specifications of Ubuntu 9.10 machine (AMD64)?
