<P>Reasonable example settings for the "couplingProperties" dictionary are given in the tutorial cases.
</P>
<PRE>modelType
</PRE>
<P>"modelType" refers to the formulation of the equations to be solved. Choose "A" or "B", according to Zhou et al. (2010): "Discrete particle simulation of particle-fluid flow: model formulations and their appliccability", JFM. "A" requres the use of the force models gradPForce and viscForce, whereas "B" requires the force model "Archimedes".
</P>
<PRE>couplingInterval
</PRE>
<P>The coupling interval determines the time passing between two CFD-DEM data exchanges.
</P>
<P>A useful procedure would be:
1) Set the DEM TS in the in.xxx according to the needs of the pure DEM problem.
2) Set the "couplingInterval", which refers to the DEM timesteps. Depending on the problem you will need to have a close (small couplingInterval) or loose coupling.
3) Choose the CFD timestep in the controlDict. it must be equal or smaller than the coupling time, otherwise you will get the error: "Error - TS bigger than coupling interval!".
</P>
<P>Example: DEMts=0.00001s, couplingInterval=10 exchange data (=couple) will happen every 0.0001s.
