LIGGGHTS 1.5.1 (released 2 Feb 2012)
CFDEM COMPATBILITY: 1.5.1 is currently not able to couple to CFDEM
+ Fixed a bug with the "riggle" for fix move/mesh/gran. Thanks to Niels Dallinger (TU Chemnitz) for noting this.
+ Fixed a bug in region block when used as wall. Thanks to Andreas Aigner (JKU) for debugging and to Moritz Höfert (BASF) for a script that showed the problem.
+ Fixed an inconsistency where the set command for property/atom had no effect when issued right after the fix. Thanks to Claudio Wolfer (NTB Buchs) for flagging this problem.
+ Fixed typos and inconsistencies in the doc of fix insert/pack, thanks to both Evan Smuts (U Cape Town) and Stefan Amberger (JKU) for bringing this up.
+ Stefan Amberger (JKU) changed the particle insertion to the newer "fix insert" commands, which replace the older fix pour and fix pour/dev commands.
+ Fixed a neighborlist issue with variable particle radius.
+ Updating the rolling friction model for pair gran/hooke was accidentally lef out in the 1.5 patch. Also fixed an issue where the rolling torque might be unitialized in rare cases. Thanks to Diego Peinado (Intrame) for noting this
+ Dump mesh/gran/VTK now can dump mesh temperature along with other quantities - thanks to user skyopener for suggesting this.
