A recent investigation to determine the best viewing configuration for any arbitrary model required me to understand the ‘QUAT’ that appears in LS-PREPOST every time you rotate a model or change its view. If you are interested to understand this, you can view this Powerpoint document for more information.

Hi Suri,
In a semi-related topic, do you know of any open-source libraries for displaying FE models? I’m basically thinking about an engine in .NET (of some flavour) that does the basics of displaying a shell/solid model with mouse pan/zoom/rotating, and perhaps something like part hiding or the like. This would most likely be a generic FE-display package that can be used for a dyna input file with a little bit of moulding-into-shape.
There have been a couple of instances where I’ve wanted to try and a custom-built program to show dyna models, but I’ve always chickened out of taking the plunge.
Cheers,
Sven.
Hi Sven,
If you are planning to do that inside a web environment, my recommendation would be to look at 3DXML or VRML2 viewers. All you need to do then is just a convertion from LS-DYNA to other formats.
If the intention is more client based, then I am afraid, I have not come across open libraries that can used to render the FEA models.
