Juan, Doing programmable selections is not well supported in Python presently. There will hopefully be future developments towards this in the near term.
For now, you can do something like: from paraview import vtk source = GetActiveSource() idss = IDSelectionSource(IDs=[0, 2, 0, 3, 0, 4], FieldType=vtk. vtkSelectionNode.POINT) ex = ExtractSelection(Input=source, Selection=idss) Show(ex) This will select points 2, 3, and 4 from the currently selected data source. Note that the list of IDs have the order [processor ID, point/cell ID, processor ID, point/cell ID, ...]. You can find documentation on additional selection types at https://www.paraview.org/ParaView/Doc/Nightly/www/py-doc/paraview.servermanager_proxies.html HTH, Cory On Thu, Apr 26, 2018 at 3:19 AM, <[email protected]> wrote: > Hello, > > I am working to make a selection of points from a unstructured grid > (associated to a .xmf file) in Paraview to carry out a FFT of them later > on.
