I found the problem ... In fact, the th z table is refering to Velocity in my case)... and the for the non-working cases, range are between [0, 0]<br>And it seems to give problems as this table is used by Glyph2 ....<br><br>

Laurent sent me the data off list. I took a look at it and determined the problem is something that has already been corrected since the 3.8 release. Here is the problem and how to fix it for those users with v3.8:<br>
<br>
clip = Clip(...)<br>...code constructs representations and sets display properties...<br>clip.ClipType.Origin = [...]<br>clip.ClipType.Normal = [...]<br><br>What is happening is the clip filter is constructed, some properties are set in the constructor, but the properties defining the clip plane are not set until the end of the python script. It is fixed by just moving the code to just after the constructor:<br>
<br>clip = Clip(...)<br>
clip.ClipType.Origin = [...]<br>
clip.ClipType.Normal = [...]<br>
...code constructs representations and sets display properties...<br><br>This issue will occur for the clip, cut, glyph, and possibly other filters. It was fixed on April 30 with git commit d9119f6be4b10 and exists in the release branch as well.<br>

Hi all,<br><br>I got some problems with the generated python code using paraview 3.8 (Python Trace State).<br><br>Using paraview GUI, I can load my pvsm file and when selecting "Glyph2" in the pipeline browser, I<br>
can set values like 'Solid Color', 'cellNormal', 'Velocity_Bis', ...<br><br>However, when executing the generated code using pvpython, I got this error:<br><br>vtkPVDReader : [ ...........]<br>vtkPVArrayCalculator : [ ...........]<br>
