</P>
|
|
<P>This "forceModel" does not influence the particles or the simulation - it is a postprocessing tool! The total volume of the particles as they are represented on the CFD mesh is calculated. Further the total volume of the cells particles are in is calculated.
|
|
At "writeTime" a field named particleCellVolume , where scalarField is the name of the original field, is written. This can then be probed using standard function object probes. Analogously a field named cellVolume is written. Using the verbose option a screen output is given.
