status: Update recommended!
changes and new features:
+ in "couplingProperties" the model type must be specified, see Zhou et al. (2010): "Discrete particle simulation of particle-fluid flow: model formulations and their appliccability", JFM
+ modified ErgunTestMPI, now showing min. fluidization velocity test
+ testcase now operate at rho != 1, to prevent from rho related bugs
+ changes in averagingModel (UsNext/Prev no longer have to be specified)
+ changes in implicitCouple (KslNext/Prev no longer have to be specified)
+ changes in explicitCouple (fNext/Prev no longer have to be specified)
+ changes in voidFractionModel (voidfractionNext/Prev no longer have to be specified)
+ new locate model engine (much faster!)
+ new voidfraction model divided (more accurate!)
+ new force model noDrag
+ new force model gradPForce
+ new force model viscForce
+ new coupling Model noCouple
+ new handling of the viscous term of the momentum balance (thx to Alice and Klemens)
+ bugfixes
