39C 'alefvm' is related to a collocated scheme (based on Godunov scheme)
40C which was temporarily introduced for experimental option /INTER/TYPE22 (FSI coupling with cut cell method)
41C This cut cell method is not completed, abandoned, and is not an official option.
42C There is no other use for this scheme which is automatically enabled when /INTER/TYPE22 is defined (INT22>0 => IALEFVM=1).
43C
44C This subroutine is treating an uncut cell.
