LIGGGHTS 2.0.4: (released 20 July 2012)
+ Andreas Aigner (JKU) made an an update to the SPH models: he added 2D-sph-kernels and fixed a bug in the wendland kernel
+ Christian Richter (OVGU Magdeburg) contributed variable-style mesh movmement for fix move/mesh: linear/variable and rotate/variable
+ Fixed a bug in fix move/mesh where the mesh was was not rotated correctly when the rotation origin was not 0/0/0.
+ Fixed a typo in the fix wall/gran doc. Thanks to Sam Bateman (USNRL) for noting this.
+ Fixed a bug with torque calculation via fix mesh/surface/stress for moving meshes. The issue was that the torque reference point was not updated. Thanks to Ryan Houlihan (Temple U) for the note.
+ Fixed a bug in the set command where the per-particle mass was not correctly inititalized when changing the diameter
+ Fixed an issue with overlapping particles at inter-processor boundaries when fix insert/pack or fix insert/rate/region was used. Thanks to Rikio Soda (Abo University) for providing a test case that showed this
+ Fixed one more typo bug in particle insertion. Thanks to Chris Stoltz (P&G) for drawing attention to this.
+ Fixed an issue with mesh parallelization where mesh elements could be lost under some circumstances which would lead to a simulation crash
However, there are some restrictions in 2.0.4 (see below) which will be relaxed over time:
+ region tetmesh is not yet available
+ 'all_in yes' is not yet available for fix insert/stream
+ fix breakparticle/force is not yet available
