Hi everybody,


I'm trying to visualise evenly spaced streamlines, but it fails when I try to load a 2d vtk dataset that I created.



I just recently found out about evenly spaced streamlines implemented in Paraview (see. https://blog.kitware.com/evenly-spaced-streamlines-2d/).

However, it is not featured in the ThirdParty-v1712 ParaView 5.4.0.
Therefore I helped myself to the binaries of ParaView-5.5.0-Qt5-MPI-Linux-64bit binaries.



It does work with the example presented in the link above, however when I try to apply the filter to a custom 2d dataset (vtk, vtm or vtp, exported by paraview from a slice) the following error message pops up:

ERROR: In /home/buildslave/dashboards/buildbot/paraview-pvbinsdash-linux-shared-release_superbuild/build/superbuild/paraview/src/VTK/Common/ExecutionModel/vtkExecutive.cxx, line 784
vtkPVCompositeDataPipeline (0x7ae7850): Algorithm vtkEvenlySpacedStreamlines2D(0x7ae6b00) returned failure for request: vtkInformation (0x67f05d0)

  Reference Count: 1
  Registered Events: (none)

Can somebody tell me, where this error stems from, is it from my data (it does work on the example dataset) or am I missing a particular reader (non-structured vtk) or something else?


Best regards,
Felix
