[Paraview] Loading sequential VTK files all at once

[Hom Nath Gharti]

Hello,
I think you cannot use PVD file for VTK legacy file format. PVD file
can be used with XML format files for instance .vti, .vts, .vtu etc. I
am not sure what actually you want to do. If you are trying to open
your files Trace_Path_1.vtk, Trace_Path_2.vtk and Trace_Path_3.vtk for
some sort of animation, then simple way is explained here
http://paraview.org/Wiki/Animating_legacy_VTK_file_series. However, if
you want to use PVD file then I think series files should be in XML
format. XML format files are certainly much more elegant.

Good luck,
