CFDEM®coupling, LIGGGHTS® and ParScale - Announcements from the developers

CFDEM coupling version 2.4.2 released (released July 17, 2012)
by DCS computing GmbH
changes and new features:
+ bugfix in dataExchange class concerning restart functionality

LIGGGHTS 2.0.3: (released 13 July 2012)

+ Finally released a first version for fix mesh/surface/stress to perform mesh stressanalysis. Re-added the "chute_wear" example into the release, doc was also updated accordingly
+ Implemented general reverse communication for mesh properties
+ Fixed an issue with shear history transfer between co-planar faces revaled by a test harness run
+ Improved recognition of shared edges and nodes in the surface mesh implementation
+ Added a new option 'area' to dump mesh/vtk to dump the area

LIGGGHTS 2.0.2: (released 06 July 2012)

+ Added a check to fix property/global for style 'atomtypepair' that checks if the values are symmetric. Note that now style 'matrix' is not necessarliy symmetric, but 'atomtypepair' is.
+ Fixed a bug in random number generation for parallel cases when fix insert/rate/region or fix insert/pack were used. Thanks to Chris Stoltz (P&G) for sending a test case.

LIGGGHTS 2.0.1: (released 29 June 2012)

+ Fixed an issue where neighborlist build was not triggered correctly for some cases with fix move/mesh. Thanks to Peter Falkingham (Royal Veterinary College, University of London) for posting a case that showed this issue.
+ Added restart functionality for fix mesh and fix move/mesh that was missing in the 2.0 version.
+ Fixed a general bug with restart where not all atom properties were restarted correctly.
+ Fixed a two typos and omissions in the doc. Thanks to Niels Dallinger (TU Chemnitz) for noting this.

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.

LIGGGHTS 2.0 RC: (released 15 June 2012)

Major feature upgrades include:
+ Merged in more than 2 years of LAMMPS updates & patches (since 10 March 2010), see http://lammps.sandia.gov/bug.html
+ New syntax for many commands, yielding a hopefully clearer input script. For details, see doc/liggghts_2.X_tutorial.html in the LIGGGHTS tarball
+ All-new mesh implementation, featuring:
+ + modular mesh design using property storage class
+ + fix mesh is now faster due to reworks in mesh topology

CFDEM coupling version 2.4.0 released (released June 06, 2012)
by DCS computing GmbH
changes and new features:
+ designed to work with OpenFOAM(R)-2.1.x
+ designed to work with LIGGGHTS 1.5.3
+ the git repository now lives at github (thx to Stefan Amberger)
+ new file structure in the directories /applications /src /doc /tutorials
+ new installation routine (see node/237)
+ new basic documentation in /doc. Please feel free to contribute.
+ new doxygen

LIGGGHTS 1.5.3 (released 22 May 2012)

+ Fixed an insertion bias in fix insert/stream. Now the stream is more continuous. Thanks to Christian Richter (OVGU Mageburg) for noting this
+ Fixed some small inconsistencies when checking for overlaps in fix insert/pack
+ Fixed an issue with region tetmesh when used with 'side out'
+ Added a new makefile by Christoph Goniva to ease compilation together with the CFDEMcoupling
