[Branch ~yade-dev/yade/trunk] Rev 1995: Beginning of adapting code about simple shear (to train with bzr almost)

 

------------------------------------------------------------
revno: 1995
committer: jduriez <jduriez@c1solimara-l>
branch nick: trunk
timestamp: Mon 2010-02-01 16:20:54 +0100
message:
  Beginning of adapting code about simple shear (to train with bzr almost)
  - There are still indeed the YADE_REQUIRE_FEATURE(PHYS_PAR) lines which prevent these files to be compiled.
  - There is only one change that will be detected by your news compilings : change of a line in ElasticContactLaw. I corrected a link towards an URL corresponding to "old 
  wiki"
  
  I made "bzr up" just before, so I hope I did nothing bad... :-~
