Thanks for the suggestion.
Yes, I tried.
At a first attempt, both SelectPoints() and SelectCells() caused ParaView to crash at the line selection=SelectPoints(). Not even an error message, the ParaView window just disappears. This seems unusual, I’ve not seen that before. I could try to narrow it down by simplifying my pipeline and see if the switch from QuerySelect(..., FieldType='CELL', ...) to SelectCells makes a difference.
Do you have any other example showing the use of SelectPoints and SelectCells? I struggle to understand the code posted by Jean M. Favre on Oct. 1, 2018. According to the documentation of SelectPoints, the only arguments of SelectPoints() are query and proxy. But the post suggests to define FieldType and QueryString after SelectPoints. selection=SelectPoint() defines that points shall be selected. I don’t get the point (
) of selection.FieldType='POINT' two lines later in that post.
