LIGGGHTS 2.3.5: (released 6 June 2013)
+ Included a commit and couple of fixes by Richard Berger (JKU) to ensure Windows compilation. Thanks to Richard and also to Christian Richter (OVGU Magdeburg) for an initial proposition.
+ Added an error check to the fix mesh/* commands to check for illegal rotation axis (such a 0,0,0)
+ Andreas Aigner (JKU) added an 'epsd2' rolling friction model, which is a variant to the recently-added EPSD model. Thanks to Andreas and to Christian Richter (OVGU Magdeburg) for helpful discussions.
+ Included a patch of Stefan Radl's group (TU Graz) who improved the compute nparticles/tracer/region command so that it computes and outputs more detailed information.
+ Fixed a bug with the newly introduced improvement of wall contact tracking for non-history wall styles (e.g. wall/gran/hooke, wall/gran/hooke/stiffness) which could lead to a program crash. Thanks to Daniel Queteschiner (JKU) for sending a test case that showed the issue.
+ Fixed a bug when restarting the simulation and a fix insert/* command should continue insertion. Somethimes this did not happen. Thanks to C. Toppin (Overland Conveyor) for posting a test case.
However, there are some restrictions in 2.3.5 (see below) which will be relaxed over time:
+ fix breakparticle/force is not yet available
BACKWARD COMPATIBILITY: Compute nparticles/tracer/region does now compute a vector, not a scalar
