Hi, all:

I am about to release the viscous damping code for YADE SVN, this damping is different from the non-viscous damping and the damping effect only exist when particles are in contact, the basic equations are similar to:

http://en.wikipedia.org/wiki/Damping

In some conditions, this is more realistic than the non-viscous damping. Two verification problems are listed in:

Feng Chen, Eric. C. Drumm, and Georges Guiochon „Prediction/Verification of Particle Motion in One Dimension with the Discrete-Element Method”. International Journal of Geomechanics, ASCE, Volume 7, Issue 5, pp. 344-352 2007 

One thing is I only tested it with YADE-0.11.1, it might take some time to compile with the latest SVN, hope this would be helpful.

Merry Christmas!

Best regards,
