Carolin, Check this post out: https://blog.kitware.com/improved-vtk-numpy-integration-part-5/
The input to your filter as a vtkMultiBlockDataSet with each block being a timestep, you can access individual arrays as described in the post or you can use the following approach: from paraview.vtk.numpy_interface import dataset_adapter as dsa dataset_time0 = dsa.WrapDataObject(inputs[0].GetBlock(0)) dataset_time1 = dsa.WrapDataObject(inputs[0].GetBlock(1)) etc. Utkarsh On Thu, Jan 11, 2018 at 5:34 AM, Carolin Helbig <carolin.hel...@ufz.de> wrote: > Dear Utkarsh, > > thank you very much for your help.
