[Paraview] Problem applying StreamTracer Filter

[Fred Fred]

Hello,I think the problem is your dataset has no cell, just points, hence Glyph generation works well because it consists in drawing a glyph at a subset or every point.But computing streamlines requires compute trajectories, ie to evaluate the flow at arbitrary points.this is achieved by interpolation within cells and if there is no cell, no interpolation scheme exists.So my advice: compute a tetrahedralization of your point cloud so as to create a valid unstructured point dataset and it should work well.Regards

    Hello everyone,

    

    I am trying to visualize my Data with Paraview 3.12.0 by exporting
    velocity vectors to an unstructured grid that is saved as a xml vtu
    file. So far the Glyph representation worked out great, but I
    couldn't get the streamtracer to work with my data. I directly
    applied it to the vectors, but there where no lines with all
    parameters I've tried.

    I've attached an example of the data. 

    Could someone please point out my mistake?

    

    Thanks for looking into this.

    

    Cheers, 

    Arne
