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.

LIGGGHTS 3.0.1: (released 10 April 2014)

LIGGGHTS 3.0.0: (released 23 January 2014)

Changes from LIGGGHTS 3.0.0-beta to LIGGGHTS 3.0.0:

LIGGGHTS 3.0.0-beta preamble: (released 03 December 2013)

Dear LIGGGHTS user community,

as you might know, LIGGGHTS has not been designed from scratch, but rather grew organically, with inputs from fields as diverse as molecular modelling, fluid mechanics, chemical engineering, mechanical enigineering, bulk solids handling, high performance computing and some more. We have seen applications across a multitude of disciplines of science and engineering, and we're very happy about that.

LIGGGHTS 2.3.8: (released 10 October 2013)

LIGGGHTS 2.3.7: (released 6 September 2013)

LIGGGHTS 2.3.6: (released 2 July 2013)

+ Added post-processing capability to fix heat/gran/conduction, which now also calculates and stores directional heat flux. Thanks to Stefan Radl (TU Graz).
+ Some enhancements to fix massflow/mesh, which is now also working with curved geometries. Thanks again to Stefan Radl (TUG).
+ Added a more clear error message in case mesh elements are lost due to moving out of the domain.
+ Fixed a rare bug with read_data associtated to initialization of atom data

CFDEMcoupling version 2.5.5 released (released June 13, 2013)
by DCS computing GmbH
+new new weight function in the voidfraction models to tune the particle volume considered in the CFD domain
+new postprocessing force model to calculate the total particle volume in the CFD domain (particleCellVolume) - see ErgunTestMPI case.
+bugfixes

LIGGGHTS 2.3.5: (released 6 June 2013)

LIGGGHTS 2.3.4: (released 17 May 2013)

+ Fixed a bug in yesterday's release of the new EPSD (elastic-plastic spring-dashpot) rolling friction model, implemented by Andreas Aigner (JKU). See Ai et al, Powder Technology, 206 (3), 269–282 for details on the model.

However, there are some restrictions in 2.3.4 (see below) which will be relaxed over time:
+ fix breakparticle/force is not yet available
