Add an optional boolean switch to standardRecModel class to allow ignoring the 0 directory when building the recurrence data base. This is useful when using rStatAnalysis as a post-processing tool on a case where OpenFOAM's purgeWrite feature was used. If purgeWrite is set to 0, then all time steps will be written to disk. If purgeWrite is set to N, then only the last N time steps will be stored. As a new time step is written to disk, the oldest one will be discarded. However, the 0 directory is excluded from removal. If purgeWrite is set to 5, and we run a simulation with deltaT=1 und endTime=10, then the time steps on disk will be: 0, 6, 7, 8, 9, 10. Running rStatAnalysis on this case, will end in fatal error, as the time step within the data base will be found to be non-uniform. The quick and dirty fix, would be to remove or rename the 0 directory, so that it does not get read. However, telling the recurrence model whether to include 0 or not seems the more elegant solution.

Description
This code provides models and solvers to realize coupled CFD-DEM simulations
using LIGGGHTS and OpenFOAM.
Note: this code is not part of OpenFOAM (see DISCLAIMER).
\*---------------------------------------------------------------------------*/
CFDEM(R) coupling provides an open source parallel coupled CFD-DEM framework
combining the strengths of the LIGGGHTS(R) DEM code and the Open Source
CFD package OpenFOAM(R)(*). The CFDEM(R)coupling toolbox allows to expand
standard CFD solvers of OpenFOAM(R)(*) to include a coupling to the DEM
code LIGGGHTS(R). In this toolbox the particle representation within the
CFD solver is organized by "cloud" classes. Key functionalities are organised
in sub-models (e.g. force models, data exchange models, etc.) which can easily
be selected and combined by dictionary settings.
The coupled solvers run fully parallel on distributed-memory clusters.
Features are:
- its modular approach allows users to easily implement new models
- its MPI parallelization enables to use it for large scale problems
- the use of GIT allows to easily update to the latest version
- basic documentation is provided
The file structure:
- "src" directory including the source files of the coupling toolbox and models
- "applications" directory including the solver files for coupled CFD-DEM simulations
- "doc" directory including the documentation of CFDEM(R)coupling
- "tutorials" directory including basic tutorial cases showing the functionality
Details on installation are given on the "www.cfdem.com"
The functionality of this CFD-DEM framwork is described via "tutorial cases" showing
how to use different solvers and models.
CFDEM(R)coupling stands for Computational Fluid Dynamics (CFD) -
Discrete Element Method (DEM) coupling.
CFDEM(R)coupling is an open-source code, distributed freely under the terms of the

Core development of CFDEM(R)coupling is done by
Christoph Goniva and Christoph Kloss, both at DCS Computing GmbH, 2012
