Hi. Now i am simulating a case where spherical particles are spreading on a 
substrate imported from a stl mesh. The number of the spherical particles is 
6,000 and the number of the facets from stl mesh is 447,262.  The calculation 
speed is low as 2~4 iter/s. 

I had tried to use more threads by the command of "yade -j4 myscript.py", 
however, i got the warning that there are fewer particles nad only some threads 
are used.  

Since the thread option doesn't work, i am wondering how to deal with a large 
number of facets to increase calculation speed?  

P.S. My system is ubuntu 18.04, yade version is 2018.02 and my cpu is intel 
i7-8or9 (quite new one, 12 threads in total).
