Generate Volume Density Data from specific region
 
I tried to run the population balance equation tutorial simulation which located at

Code:
$FOAM_TUTORIALS/multiphase/multiphaseEulerFoam/RAS/bubblePipe
in the post-processing directory, it generate the volumedensity data from injector region that defined using topoSet command. The volumeDensity data is generated using function object in controlDict. The function is probabilityDensity. This below is the controlDict file

https://github.com/OpenFOAM/OpenFOAM...em/controlDict

My question is,
1. How to use the probabilityDensity function in specific 3D region/point/area?
2. Should I use topoSet utility first to generate region?
thanks in advance
