Paraview data format conversion from vtk to parallel prog data format.
 

hi
I have to change the current data format which is written to save the data in vtk format to parallel prog format

I have seen the data format but i couldnot change it.

i am using fortran language.

here are the subroutines
================================================== ===================
!-------------------------------------------------------------------------------------------------
subroutine print_fronts2(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)//'.vtk')

do i = 1, myNumFronts

write(iunit,10)
write(iunit,11)time
write(iunit,12)
write(iunit,13)
10 format('# vtk DataFile Version 2.0')
11 format('grid, time ',F16.8)
12 format('ASCII')
13 format('DATASET POLYDATA')
call print_2(my_Fronts(myFronts_IDs(i)),iunit,xh,yh,zh, dx,dy,dz,Nx,Ny,Nz,Ng,Nxt,Nyt,Nzt,xLength,yLength,z Length)

enddo
close(iunit)
end subroutine print_fronts2
================================================== =====================subroutine print_2(this,iunit,xh,yh,zh,dx,dy,dz,Nx,Ny,Nz,Ng,N xt,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), 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
real(8) :: xp(3)


write(iunit,15)this%PointLength
15 format('POINTS ',I17,' float' )

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)
WRITE (iunit,255) xp
255 FORMAT (' ',3E13.5)
enddo

write(iunit,16) this%ElemLength,4*this%ElemLength
16 format('POLYGONS ',2I17)
do elem = 1, this%ElemLength
call write_integer(iunit,3,this%ElemCorner(1,elem),this %ElemCorner(2,elem),this%ElemCorner(3,elem))
266 FORMAT (' 3',3I6)
enddo

end subroutine print_2
