LIGGGHTS 3.0.2: (released 12 June 2014)

Important note for CFDEMcoupling users: There has been a slight patch in CFDEMcoupling to make it compile with LIGGGHTS 3.0.2. Please perform a "git pull" for CFDEMcoupling.

+ Added a new 'contact_area' keyword to the fix heat/gran/conduction and fix wall/gran command, that serves to provide different choices of how particle-particle and particle-wall contact area for heat conduction is calculated
+ Added a feature to fix couple/cfd/force so that LIGGGHTS can send an arbitrary addtional property to CFDEMcoupling if needed
+ The group of Stefan Radl (TUG) added an implementation which removes the "force artifact" that normal models show attractive forces during the repusion phase of the collision. Please note that in the current implementation the coefficient of restitution will not be recovered. Thanks for providing this!
+ Richard Berger (JKU) made some changes in the inner working of contact models. Please see the LIGGGHTS developers wiki on https://github.com/CFDEMproject/LIGGGHTS-PUBLIC/wiki for details
+ Richard Berger (JKU) made a small update to the LIGGGHTS MPI wrappers, which could give some performance improvements for large-scale simulations
+ Richard Berger (JKU) fixed issues with argument parsing of fix wall/gran
+ Christian Richter (OVGU Magdeburg) found a bug in fix gravity, when using it in the variable-style. Thanks for flagging this!
+ Tijmen Ton (Twister BV) sent a test case revealing that for some cases memory overflow was not correctly caught for mesh contact history. This is now fixed.
+ Fixed a small issue with dumping mesh temperature via the dump mesh/vtk keyword
+ Fixed several minor memory leaks
