Visualizing Bonds and Stress Chains

Asked by Zachary Koszegi-Faulkner

Vaclav,

Two questions!

In your example on youtube (https://www.youtube.com/watch?v=8dc7NecQ1s0) you show bonds between particles being visualized, I was wondering how to do this in Woo[dem].
Previously in Yade I had used:

     exporter=export.VTKExporter(filepath+'/results')
     exporter.exportInteractions(what=[('adn','i.phys.normalAdhesion'),('ads','i.phys.shearAdhesion')])

But I can't seem to find a similar, or any method in Woo.

The second question I have is about visualizing stress chains similar to this video of LIGGGHTS https://www.youtube.com/watch?v=o4nUsNPXuAs, is it possible in Woo, and if so, how?

Hi Zachary,

I put together a new doc page, since visualization was in need of being documented properly (not that this is final, but it should be enough to get you oriented): http://woodem.eu/doc/user/visualization.html .

Basically you can do visualization in the 3d view during simulation (generally more flexible and made for DEM, but only given simulation moment is seen; lacks some features like opacity) or from data exported for Paraview (less tailored for DEM, you can go through the whole simulation in steps, the visualization quality is very good).

I hope this helps you.

Cheers!
