particle tracer error: Number of components do not match

ParaView Support

hello, i want to trace some particles injected to a domain where i know the velocity field data for every time step. I have already created a .pvd file containing the data in order to import it to paraview. Now when it comes to using the Particle tracer filter, i get the following error messages:

ERROR: In vtkGenericDataArray.txx, line 63

vtkTypeFloat64Array (000001F993D4B340): Number of components do not match: Source: 3 Dest: 1

vtkTypeFloat64Array (000001F9FD76B060): Number of components do not match: Source: 1 Dest: 4

and so on…

Do you have any idea regarding to those errors? Besides the errors, the animation of the filter seems to work. I insert the calculated velocity field as an input to the filter and a line as a seed source. Here is also the .pvd file that i am using.
all_results.pvd (20.0 KB)
Any idea would be much appreciated!

Generally this happens with the particle tracer filter when there is a different number of arrays or the arrays that are available are ordered differently in the input dataset to the filter. A .pvd file is only a meta-file so I can’t see your actual data.

thank you for your answer Andy! Here you can find my actual data: vtu files for PT - Google Drive
