LIGGGHTS 2.0: (released 26 June 2012)
+ Made a final syntax change - fix mesh/surface is now the syntax for a surface mesh in LIGGGHTS. Also removed the backward compatibility to the fix mesh/gran syntax as this would have lead to troubles sooner or later.
+ Removed package "GRANULAR" as its files are already present in the core of LIGGGHTS - this should help to avoid confusion and unwanted file destruction.
+ Fixed a machine-dependant compilation issue. Thanks to Christian Richter (U Magdeburg) and Mark Bentley (Space Reseach Institute, ÖAW) for pointing this out.
+ Fixed another compilation issue when compiling with the MPI stubs library. Thanks again to Mark Bentley (Space Reseach Institute, ÖAW) for noting this.
+ Added some files necessary for the SPH models which were accidentially left out in the 2.0RC version. Thanks to Andreas Aigner (JKU) for noting this.
+ Added a "region wedge" command written by Stefan Amberger (JKU).
+ Fixed a bug related to unfixing of fix move/mesh commands. Thanks for Moritz Höfert (BASF) and Philippe Seil (JKU) for noting this.
+ Fixed a bug related to the fix insert/rate/region command. Thanks to Chris Stoltz (P&G) for reporting this.
+ Fixed a couple small memory leaks.
+ Introduced a couple of cosmetic changes for internal use of vector functions and MPI wrapper functions.
+ Fixed an issue with fix transportequation/scalar (used by fix heat/gran) where the quantity to be calculated was not forward communicated to some ghosts correctly on reneigh steps.
+ Fixed a small issue with correct damping in pair gran and fix wall/gran for particles that are part of a fix rigid. Thanks to Steve Plimpton (Sandia) for code snippets and a helpful discussion.
However, there are some restrictions in 2.0 (see below) which will be relaxed over time:
+ restart for fix mesh is not available, but will be released shortly
+ region tetmesh is not yet available
+ fix mesh/gran/stressanalysis is not yet available
+ 'all_in yes' is not yet available for fix insert/stream
+ fix breakparticle/force is not yet available
