Hi,
I’m trying to read my first .vtk file, but Paraview says that he can’t find a reader for the file. Guess there is something wrong with my file. Can someone help me with this?

This file is incorrectly formated, how was it written ?

With this FORTRAN 03 subroutine:
```
subroutine visualplanoXY(var,plano)
use modvar
implicit none
integer ii, jj, kk, plano
real (kind = 8) x, z, var(nx,ny,nzt)
! writes data to be open by paraview
open (3, file = 'variavel.vtk',status = 'unknown')
write(3,*)'# vtk DataFile Version 2.0'
write(3,*)'variavel.vtk'
write(3,*)'ASCII'
write(3,*)'DATASET STRUCTURED_GRID'
write(3,*)'DIMENSIONS',nx,ny
write(3,*)'POINTS',nx*ny,'float'
do jj = 1, ny
do ii = 1, nx
x = dble(ii-1) * dx
write(3,71) x, y(jj)
end do
end do
write(3,*)'POINT_DATA',nx*ny
write(3,*)'SCALARS var float 1'
write(3,*)'LOOKUP_TABLE default'
do jj = 1, ny
do ii = 1, nx
x = dble(ii-1) * dx
write(3,72)var(ii,jj,plano)
end do
end do
close (unit = 3)
71 format(2(1x, ES13.6E2))
72 format(1x, ES13.6E2)
```

Looks like you are trying to write 2D data ?
[https://docs.vtk.org/en/latest/design\_documents/VTKFileFormats.html#dataset-format](https://docs.vtk.org/en/latest/design_documents/VTKFileFormats.html#dataset-format)
There is not 2D data in VTK, only 3D.

Was I supossed to add a third column full of zeros for z-axis? I tried this and still don’t work. Thank you for the fast replies.

You need to remove the leading space on each line, like this:
