Description

Note

This forceModel does not influence the particles or the flow. It is a postProcessing tool.

This model calculates a local concentration of particle type A defined as the ratio between the volume of particles of type A $V_\mathrm{A}$ and B $V_\mathrm{B}$ within a cell: $c = \frac{V_\mathrm{A}}{V_\mathrm{A} + V_\mathrm{B}}$ .

The concentration of type B is not computed separately but is then available as $1 - c$ .

Note

Volume calculation is performed under the assumption of spherical particles. For nonspherical shapes this may result in inaccurate results.

Restrictions

None.
