40C 'alefvm' is related to a collocated scheme (built from FVM and based on Godunov scheme)
41C which was temporarily introduced for experimental option /INTER/TYPE22 (FSI coupling with cut cell method)
42C This cut cell method is not completed, abandoned, and is not an official option.
43C There is no other use for this scheme which is automatically enabled when /INTER/TYPE22 is defined (INT22>0 => IALEFVM=1).
44C
45C This subroutine is treating an uncut cell.
