Jerome Duriez (12):
      +1 journal paper
      Incorporating previous +1 paper in JCFpm doc
      + another journal paper
      makeCloud doc changes with the hope to make it clearer for all users
      Doc of TriaxStressController.porosity precised
      Doc improvements of previous commit improved
      Last doc improvement of previous commit
      normalForce and shearForce convention (sustained by #2) precised in docs
      fabricTensor() now ok for non-periodic simulations. revertSign attribute removed as well
      getSpheres*() functions: getting rid of dynamic test, see
      fabricTensor(): unify the behavior regarding boundary interactions whether split=0 or 1: they are now disregarded in both cases
      fabricTensor(): re introducing all kind of interactions in the loop, with the new possibility defining a cutoff. See

Klaus Thoeni (23):
      fix some typos and add some more details
      fix Anton's previous commit (make doc was not working)
      fix documentation for Note
      some polishing
      gts shift and scale apparently only take three float values, hence changed
      Merge branch 'master' of
      move grid specific functions in separate module and add some more doc
      add some more examples, show same functionality as with chained cylinders
      update doc
      add Grid and pFacet references
      Initial version of the PFacet implementation (contributed by Anna Effeindzourou)
      Examples for creating pfacets
      update tests according to new gridpfacet module

      add reference

Raphael Maurin (6):
      HydroForceEngine: modify the turbulent fluctuations formulation and add a new DRW model The turbulent fluctuations model takes now the form of a function of HydroForceEngine and is not anymore called from a flag. In addition, an alternative DRW model has been added.
      HydroForceEngine: adapt the averageProfile function for bi-disperse mixtures. Evaluate the streamwise, spanwise and wall-normal average particle velocity for the two defined types of particles.
      HydroForceEngine: modify turbulent fluctuation model. Add a fluctuation along the spanwise (y) direction. Reset the fluctuation to zero when the particle is out of the flow (fix a bug) Comment a bit more the turbulentFluctuation function
      HydroForceEngine, hpp file completing the last commit
      Add references
      add a link in the publications
