LIGGGHTS 1.2.4 beta (released 1 February 2011)
+ Updated the new shear history formulation - now dissipation comes from either sliding or damping, not from both.
The way it was done in 1.2.3 beta produced unreasonable results, e.g. for the conveyor test case
+ Fixed a bug with deleting a mesh wall during the simulation - thanks to Diego Peinado (Intrame) for catching this.
+ Fixed a typo bug in the new contact history. Thanks to Jean Francois Jerier (EPFL) for finding this tricky issue.
+ Fixed a restart bug - thanks to Ram Chand for reporting this
+ Fixed a bug in the communication of pair gran and compute pair/gran/local
+ Corrected the doc regarding rollingfriction - thanks to Christian Grohs (Plansee) for finding this
IMPORTANT NOTE: This version is in beta state.
