[Paraview] Problem with Temporal Cache

[Mohamad M. Nasr-Azadani]

Hi,

I am doing a simple experiment.
I load a *.PVD file (time aware) which looks like this:


<?xml version="1.0"?>
 <VTKFile type="Collection" version="0.1" byte_order="LittleEndian"
compressor="vtkZLibDataCompressor">
   <Collection>
    <DataSet timestep="0.0" group="" part="0" file="vel_vec_0.vtr"/>
    <DataSet timestep="0.2" group="" part="0" file="vel_vec_1.vtr"/>
    <DataSet timestep="0.4" group="" part="0" file="vel_vec_2.vtr"/>
    <DataSet timestep="0.6" group="" part="0" file="vel_vec_3.vtr"/>
    <DataSet timestep="0.8" group="" part="0" file="vel_vec_4.vtr"/>
    <DataSet timestep="1.0" group="" part="0" file="vel_vec_5.vtr"/>
    <DataSet timestep="1.2" group="" part="0" file="vel_vec_6.vtr"/>
    <DataSet timestep="1.4" group="" part="0" file="vel_vec_7.vtr"/>
    <DataSet timestep="1.6" group="" part="0" file="vel_vec_8.vtr"/>
    <DataSet timestep="1.8" group="" part="0" file="vel_vec_9.vtr"/>
    <DataSet timestep="2.0" group="" part="0" file="vel_vec_10.vtr"/>
  </Collection>
</VTKFile>

Then, I apply a Temporal Cache [Cache size = 2] (or similarily Temporal
Interpolator [Discrete Timestep Interval=0.1]) to the loaded dataset.

Then, I create a simple "Slice" filter on my dataset, as soon as I play
animation, Paraview gives this Error message or sometimes crashes. (PV
3.14, on Ubuntu).

  ERROR: In
/home/utkarsh/Kitware/superbuild/paraview/src/paraview/VTK/Filtering/vtkStreamingDemandDrivenPipeline.cxx,
line 934

vtkPVPostFilterExecutive (0x3035620): No maximum number of pieces has been
set in the information for output port 0 on algorithm
vtkPVPostFilter(0x3347630).


What is it that I am doing wrong?


Cheers.

Mohamad
