Then use that as your Seed Source.Īnother (probably better) option if your data is 2D or you can extract an interesting surface along the flow of your data is to use the Surface LIC plugin. One thing you might want to try is to compute the vorticity of your vector field ( Gradient Of Unstructured Data Set when turning on advanced option Compute Vorticity), find the magnitude of that ( Calculator), and then use the Threshold filter to pull out the cells with large vorticity. Thus, you are better off with trying to derive a data set that contains seed points that are likely to trace a stream through the vortices that you are interested in. You will get all those interesting streamlines through vortices, but they will be completely hidden by all the boring streamlines around them. Even worse, the result will be so dense that you won't be able to see anything. First of all, unless your data is trivially small, this will take a long time to compute and create a large amount of data. However, while you can do this, you will probably not be happy with the results. That will create a streamline originating from every point in your dataset, which is pretty much what you asked for. DeMarle D., Geveci B., Ahrens J., Woodring J.To add a little bit to Mathieu's answer, if you really want streamlines everywhere, then you can create a Stream Tracer With Custom Source (as Mathieu suggested) and set your data to both the Input and the Seed Source. Using the Paraview API from paraview.simple import cylindervtk LegacyVTKReader (FileNames.

Using Python, users and de-velopers can gain access to the ParaView engine called Server Manager1. This support is available as part of the ParaView client (paraview), an MPI-enabled batch application. This support is available as part of the ParaView client (paraview), an MPI-enabled batch application (pvbatch), the ParaView py-thon client (pvpython) or any other Python-enabled application. ParaView offers rich scripting support through Python. James Ahrens, Sébastien Jourdain, Patrick O’Leary, John Patchett, David H Rogers, Mark Petersen.
