Multi Phase_ Multi Pressure Cell Zone_
 

Hi Dear Engineers .
i have a Model For Trace Methane Leak In Gas station -
at the Present I have Some Question :

1: after selecting Multiphase Model and Define Cell Zone As Pic - i need To Define cell Different Properties after Initialize , in Patch Window I want Define coefficients such Volume Fraction and Cell Pressure but There aren't Some Variables Such Pressure which I need , I try to Define Field Function But It does not work Properly and Effect on Volume Friction Variable , Now How I Could To define These Coefficients?

2:Can I define Material Properties by Use Of Piece Wise Liner or Polynomial Function that Set By Pressure ( Not Temperature ) or need to UDF ?



Thanks so much for the helps from friends
