C Interface Type22 (/INTER/TYPE22) is an FSI coupling method based on cut cell method. 
C   This experimental cut cell method is not completed, abandoned, and is not an official option.
C
C this subroutines update VOLN for cut cells.
C Main cells have extended values of volume due
C to secnd cell merging. This extension data is 
C stored in cut cell buffer and is now used here
C to update VOLN(*)
