This is a scaled down version of the previous test. Particle diameter: 350 micrometers. Glass particles, steel geometry.

This is a comparison between the built-in contact model in EDEM and the stress tensor contact model plug-in. The contact model in the plug-in should be the same as the built-in one, as the code was provided with EDEM. I have made this video to check that the first particle does in fact bounce using the plug-in and not just vibrate as it did in the larger scale sim. The first particle appears to not bounce as high using the plug-in contact model. I did a second simulation of this in EDEM with the plug-in, and the particle had a bounce just as high as the built-in model.

The difference was that in the second test (not shown here) I recreated the environment from scratch. My guess is that this means that EDEM has some problems in switching from one plug-in to another that uses the same custom particle property. It seems that EDEM is not completely erasing the old custom particle property before using the new one. So you must recreate your sim environment rather than editing an old one if you plan to switch to a new plug-in that uses the same custom particle property as the old one (stress, for example).
