Population balance model – Using the Inhomogeneous discrete method

      Hey


       


      I have two questions about using the inhomogeneous discrete method.


      1) How exactly do you define a binsize file? I tried to define it for two phases in a .txt file like:


       


      (("phase-2" (0.1 0.2 0.3))


      (("phase-3" (0.01 0.02 0.03))


       


      But this doesn't seem to work.


       


      2) When I want to model two phases with the same sizes of particles (see example in figure)


      , I get an error "Binsizes for secondary phases are overlapping". Is there an easy way around this error that allows to use two phases with the same binsizes?


       


      Thanks in advance!


      Vince

      What happens if you drop to 1 active secondary phase & set up for "phase-2" and "phase-3" under "phase"? It's greyed out in your model.

      Hey, thanks for the reply. The "phase" seems always to be greyed out for the Inhomogeneous discrete method, so I can't play around with that. The main problem I'm having now is that I don't know how to write a Binsize file (textfile) for this method.


      For the discrete method the textfile looks like (e.g. for 3 bins with sizes 0.1 0.2 0.3)


      0.1
      0.2
      0.3
      3


      But I don't manage to produce a valid file for the inhomogeneous discrete method.
