Hi every one

I want an UDF for variable x that vary with ratio of volume fraction of a phase to the total volume (in multiphase system). I mean that based on ratio of volume fraction of a specific phase to total volume as fluid flows, the variable x varies. For example for total volume of 100 m3, if volume fraction of phase “A” is 0 (0/100) the variable x = 10. If volume fraction is 10m3 (10/100) the variable x =20 and so on.

I would be very appreciated if you could help me on this
