Hi, <div><br></div><div>I am doing a simple experiment. </div><div>I load a *.PVD file (time aware) which looks like this: </div><div><br></div><div><br></div><div><div>&lt;?xml version=&quot;1.0&quot;?&gt;</div><div> &lt;VTKFile type=&quot;Collection&quot; version=&quot;0.1&quot; byte_order=&quot;LittleEndian&quot; compressor=&quot;vtkZLibDataCompressor&quot;&gt;  </div>

<div>   &lt;Collection&gt;</div><div>    &lt;DataSet timestep=&quot;0.0&quot; group=&quot;&quot; part=&quot;0&quot; file=&quot;vel_vec_0.vtr&quot;/&gt;</div><div>    &lt;DataSet timestep=&quot;0.2&quot; group=&quot;&quot; part=&quot;0&quot; file=&quot;vel_vec_1.vtr&quot;/&gt;</div>

<div>    &lt;DataSet timestep=&quot;0.4&quot; group=&quot;&quot; part=&quot;0&quot; file=&quot;vel_vec_2.vtr&quot;/&gt;</div><div>    &lt;DataSet timestep=&quot;0.6&quot; group=&quot;&quot; part=&quot;0&quot; file=&quot;vel_vec_3.vtr&quot;/&gt;</div>

<div>    &lt;DataSet timestep=&quot;0.8&quot; group=&quot;&quot; part=&quot;0&quot; file=&quot;vel_vec_4.vtr&quot;/&gt;</div><div>    &lt;DataSet timestep=&quot;1.0&quot; group=&quot;&quot; part=&quot;0&quot; file=&quot;vel_vec_5.vtr&quot;/&gt;</div>

<div>    &lt;DataSet timestep=&quot;1.2&quot; group=&quot;&quot; part=&quot;0&quot; file=&quot;vel_vec_6.vtr&quot;/&gt;</div><div>    &lt;DataSet timestep=&quot;1.4&quot; group=&quot;&quot; part=&quot;0&quot; file=&quot;vel_vec_7.vtr&quot;/&gt;</div>

<div>    &lt;DataSet timestep=&quot;1.6&quot; group=&quot;&quot; part=&quot;0&quot; file=&quot;vel_vec_8.vtr&quot;/&gt;</div><div>    &lt;DataSet timestep=&quot;1.8&quot; group=&quot;&quot; part=&quot;0&quot; file=&quot;vel_vec_9.vtr&quot;/&gt;</div>

<div><br></div><div>Then, I create a simple &quot;Slice&quot; filter on my dataset, as soon as I play animation, Paraview gives this Error message or sometimes crashes. (PV 3.14, on Ubuntu). </div><div><br></div><div>
