mixed invasion percolation

[WTK1998]

Hi dear Dr.

1. I used invasion and mixed invasion percolation to calculate rel perm curves and results:
   
   
   and when I apply trapping:
   
   
   I'm sure in both curves x-axis is in terms of water saturation. Which curve is true?

2. mixed invasion percolation : when both of trapping and snap off are true, non wetting phase rel perm does not work:
   
   I send my code to your personal email.
   thanks.
