Hi, I'm struggling to write a script for Paraview that will let me take a slice through my vtkMultiblockDataSet and save just the slice (so all of the data on the slice and all of the points that make up the slice) in a format that I can look at later. I can get it to dump all of the data to a set of CSV files, but I can't look at those again in paraview.
My function is very simple (see below). I have tried to use CreateWriter directly with the .vtk file extension like is shown on http://www.paraview.org/Wiki/ParaView/Python_Scripting#Writing_Data_Files_.28ParaView_3.9_or_later.29 but that says the vtk file format is unknown and so it doesn't work. I have tried virtually every writer that would make sense in that writer line and none of them work properly. As it is, the one that is there now says: vtkCompositeDataPipeline (0x9ac9380): Can not execute simple alorithm without output ports and I don't know what that means or why it fails to write. (Side note -- algorithm is spelled wrong in that error message, comes from vtkCompositeDataPipeline.cxx line 168). Anybody have any suggestions or advice on how to save the datasets that results from a slice so I can look at just that slice later? Thanks, Tim def run(out_dir, file_num, spreadsheet_name, slice_origin, slice_normal, triangulate=False): restart_file = XDMFReader(FileName=out_dir+'/RESTS/rest_%05i.xmf' % file_num) restart_file_dr = Show() if triangulate: tri = 1 else: tri = 0 my_slice = Slice(SliceOffsetValues=[0.0], Triangulatetheslice=tri, SliceType="Plane" ) my_slice.SliceType.Origin = slice_origin my_slice.SliceType.Normal = slice_normal slice_dr = Show() writer = XMLUnstructuredGridWriter(Input=my_slice) writer.FileName = out_dir+"/post/"+"%s_data_%05i_.vtu" % (spreadsheet_name, file_num) writer.UpdatePipeline() _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Search the list archives at: http://markmail.org/search/?q=ParaView Follow this link to subscribe/unsubscribe: http://public.kitware.com/mailman/listinfo/paraview
