Good morning, <br><br>I have just found the following bug report about a mistake in the Q-criterion formula. <br><a href="http://paraview.org/Bug/view.php?id=12858">http://paraview.org/Bug/view.php?id=12858</a><br>that is now closed. <br>
<br>However, the "1/2" factor may still be missing. <br>In vtkGradientFilter.cxx, in the VTK/Grahpics directory, on the line 65, t1 should be divided by 2. (Paraview 3.14.1)<br><br>Should I re-open the bug report ?<br>
<br>With best regards, <br><br>Aurélien<br>
