      SUBROUTINE alefvm_gravity(VOLN, IXS, RHO)
C-----------------------------------------------
C   D e s c r i p t i o n
C-----------------------------------------------
C 'alefvm' is related to a collocated scheme (built from FVM and based on Godunov scheme)
C  which was temporarily introduced for experimental option /INTER/TYPE22 (FSI coupling with cut cell method)
C This cut cell method is not completed, abandoned, and is not an official option.
C There is no other use for this scheme which is automatically enabled when /INTER/TYPE22 is defined (INT22>0 => IALEFVM=1).
C
C This subroutine is treating an uncut cell.
