Hi
please help me regarding data format to save the results with periodic boundary condition.

Below here are two subroutines which i am using to save data.
================================================== ===================
subroutine print_fronts1(my_Fronts,my_NumFront,nf,grank,time)
use module_grid
use module_IO
use front_lib
implicit none
type(Front), dimension(, pointer, intent(in) :: my_Fronts
integer :: my_NumFront
integer :: nf, iunit, i,grank
real(8) :: time
iunit=7
OPEN(UNIT=iunit,FILE=trim(out_path)//'/front'//int2text(grank,4)//int2text(nf,4)//'.dat')
write(iunit,*)'variables = "x","y","z"' !,"u","v","w"'

do i = 1, myNumFronts

write(iunit,"('ZONE solutiontime=',1PG15.7E2,' DATAPACKING=POINT, ZONETYPE=FETRIANGLE')")time
call print_1(my_Fronts(myFronts_IDs(i)),iunit,GammaInf, xh,yh,zh,dx,dy,dz,Nx,Ny,Nz,Ng,Nxt,Nyt,Nzt, &
xLength,yLength,zLength)

enddo
close(iunit)
end subroutine print_fronts1
================================================== ===================
!-------------------------------------------------------------------------------------------------
subroutine print_1(this,iunit,GammaInf,xh,yh,zh,dx,dy,dz,Nx,N y,Nz,Ng,Nxt,Nyt,Nzt,xLength,yLength,zLength)
! use module_grid
! use module_IO
implicit none
type(Front), intent(in) :: this
integer, intent(in) :: Nxt, Nyt, Nzt ! total number of cells
integer, intent(in) :: Nx, Ny, Nz, Ng
real(8), intent(in) :: xLength, yLength, zLength, GammaInf
real(8), dimension(Nxt), intent(in) :: xh, dx
real(8), dimension(Nyt), intent(in) :: yh, dy
real(8), dimension(Nzt), intent(in) :: zh, dz
integer :: iunit, elem, point, p1, p2, p3
real(8) :: xp(3)

!--mm
this%AveGamma = 0.0d0
this%CountNgbr = 0.0d0
!--mm

write(iunit,"('NODES=',I6,' ,ELEMENTS=', I6)")this%PointLength, this%ElemLength

!--mm
!----compute the surfactant concentration at element corners
do elem = 1, this%ElemLength
p1=this%ElemCorner(1,elem)
p2=this%ElemCorner(2,elem)
p3=this%ElemCorner(3,elem)
this%AveGamma(p1) = this%AveGamma(p1) + this%gammas(elem)
this%AveGamma(p2) = this%AveGamma(p2) + this%gammas(elem)
this%AveGamma(p3) = this%AveGamma(p3) + this%gammas(elem)
this%CountNgbr(p1) = this%CountNgbr(p1) + 1.0d0
this%CountNgbr(p2) = this%CountNgbr(p2) + 1.0d0
this%CountNgbr(p3) = this%CountNgbr(p3) + 1.0d0
enddo
!--mm

do point = 1, this%PointLength
call GetCoords(this,xp,point,xh,yh,zh,dx,dy,dz,Nx,Ny,Nz ,Ng,Nxt,Nyt,Nzt,xLength,yLength,zLength)
!--mm
this%AveGamma(point) = this%AveGamma(point)/this%CountNgbr(point)
!--mm
write(iunit,'(6e16.8e2)') modulo(xp(1),xLength), modulo(xp(2),yLength), &
modulo(xp(3),zLength), this%AveGamma(point)/GammaInf
enddo

do elem = 1, this%ElemLength
call write_integer(iunit,this%ElemCorner(1,elem),this%E lemCorner(2,elem),this%ElemCorner(3,elem))
enddo

end subroutine print_1
================================================== ===================
see the result attached here with.
when bubbles are boundary which is periodic the result is not good
please help me to correct this.
thanks alot
