LIGGGHTS 1.1.9 (released 19 October 2010)

1) Added the possibility to include particle-wall heat conduction with constant wall temperatures. This is both possible for both generic and CAD walls, see fix wall/gran and fix mesh/gran for details. Also fixed an issue with the heat transfer model, where particle based heat sources/sinks could have been double counted under certain circumstances
2) George Marketos (Imperial College) sent some code to improve 2d simulations. Now, particle inertia in 2d simulations is calculated for a disk rather than for a sphere
3) Improved the restart capability of fix pour/dev: It is now possible to restart a fix pour/dev that already completed insertion in the old run by specifying a higher number of particles to insert in restart script. Thanks to Ram Chand (Chinese Academy of Science) for catching this
4) One more update to the mesh/gran command that should improve the correctness of damping for particle-triangle corner contacts
5) It is now possible to use the per-particle radius as an input for the variable command
6) Fixed an issue where variable particle mass could have led to problems in conjunction with periodic boundary conditions. Also, variable particle density is now accounted for in parallel
7) Fixed a typo in the doc for pair gran - thanks to user Yansan for catching this
