43C 'alefvm' is related to a collocated scheme (built from FVM and based on Godunov scheme)
44C which was temporarily introduced for experimental option /INTER/TYPE22 (FSI coupling with cut cell method)
45C This cut cell method is not completed, abandoned, and is not an official option.
46C There is no other use for this scheme which is automatically enabled when /INTER/TYPE22 is defined (INT22>0 => IALEFVM=1).
47C
48C This subroutine is treating an uncut cell.
