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
! Get Nodes which is the farthest from intersection points
! equivalent to calculating mean adjacent surface ratio.
