LIGGGHTS 2.3.3: (released 16 May 2013)
Hi all,
a new LPP version has been released, including various bugfixes and an update of the force network viz tool by Stefan Radl (Graz UT)
LPP is now also running on github: git@github.com:CFDEMproject/LPP.git
Cheers

CFDEMcoupling version 2.5.4 released (released Mai 16, 2013)
by DCS computing GmbH
A new sub-model class was added to allow for manually smoothing the exchange fields.
changes and new features:
+new smoothingModel class was added to cfdemCloud and used in the solvers. Two models are currently available (noSmoothing and constDiffSmoothing)
+bugfixes
Dear CFDEM community,
we're continuously working on improving the quality of our community interaction. Therefore, a planned downtime due to maintenance for the www.cfdem.com site is scheduled on May 4 and 5, 2014.
Some or all functions of the website will not be available during that time. The site should be back to normal on Moday, May 6, 2014.
On behalf of the CFDEM team,
Christoph Kloss

Dear all,
Christoph Kloss (JKU, DCS Computing,) Stefan Pirker (JKU), Christoph Goniva (JKU, DCS Computing), Stefan Radl (TU Graz) and Simon Schneiderbauer (JKU) are organizing a Mini-Symposium entitled
" Modelling of Medium to Dense Fluid-particle Flows"
CFDEMcoupling version 2.5.3 released (released April 8, 2013)
by DCS computing GmbH
As important changes for better stability compared to the previous versions were made, an update is recommended!
changes and new features:
+bugfix for writeLiggghts liggghts command model (continuously writing restart files). Changes in dataExchangeModel.H
+bugfix in CFD sub time stepping related to (timeStepFraction calculation, KslNext/Prev and voidfractionNext/Prev)
+new handling of ddt(voidfraction) - normally off
LIGGGHTS 2.3.2: (released 29 March 2013)
+ Patched a memory issue that came in with yesterday's release of shear history handling for primitve walls
However, there are some restrictions in 2.3.2 (see below) which will be relaxed over time:
+ fix breakparticle/force is not yet available
LIGGGHTS 2.3.1: (released 28 March 2013)
+ Released a new fix couple/cfd/force/implicit for use with CFDEMcoupling that uses a dragforce that varies with particle velocity rather than a constant one on the DEM side.
A couple of small updates for fix insert/*:
+ Added output of fix-ID to insertion info, which can be helpful in case multiple insertions are used.
+ Fixed an issue where in some cases no particles were inserted for cases with large # of procs (e.g. 128). Thanks to Sam Bateman (USNRL) for bringing this up.
CFDEM coupling version 2.5.2 released (released March 19, 2013)
by DCS computing GmbH
changes and new features:
+ new sophIO model writing drag forces
+ IO model now by default write in parallel format
+ cfdemPostproc now also writes the lagrangian data using the IO model
+ KochHill drag force model can be used with implicit drag formulation on DEM side (with the next LIGGGHTS release)
+ new example using CGS unit system (thx to Evan for the support)
