Hi everyone,

I'm trying to simulate clump interactions using version 1.20 of YADE and this process goes much more slower than in versions 1.12 and earlier. Do you know why? 

my test:https://www.dropbox.com/s/zbr4adcb0ox2ir4/test3.py?dl=0

The number of bodies is probably too small for allowing more threads, or the geometry is flat. The contact detection should succeed but not all available threads are used.
