Im using paraview 5.4. and could not find any reader in paraview to load my .vtk files.While opening the files it shows a message like this and a list of readers are shown. If I select the vtkparticle files reader, the paraview doesnt show any particles there in the interface. Can you plz suggest me a solution for this.

You .vtk file is invalid, that is why ParaView can’t open it.

Sir these vtk files are the result files of a simulation done in LIGGGHTS (ubuntu). Two of my result files are here attached with this message. These vtk files represent particles which are entering into a screw conveyor.

Your file are not in the vtk format, but `LAMMPS atom style dump file format`
[https://www.ks.uiuc.edu/Research/vmd/plugins/doxygen/lammpsplugin\_8c-source.html](https://www.ks.uiuc.edu/Research/vmd/plugins/doxygen/lammpsplugin_8c-source.html)

You have to save into a format recognized by ParaView.
