Pick on derived expressions on a boundary surface. #12330

@burton29-LLNL, moved this from the older issue since it is a new question.

Hi,

New question: I’m using Version 3.1.3 (August 2020), and got a question about examining nodes and zones through “Pick”, on derived new expressions on a boundary surface. I’ve got a velocity field defined on a surface, and I want to extract that part of the velocity field that is perpendicular to the surface. So generating an “external surface” and then using the DeferExpression workflow that I’ve developed previously, I generate a pseudo-color plot of this derived field I’m calling “V_perp_mag” which looks reasonable. However, when I try using “Pick” on one of the surface zones or nodes, Visit gives me a message “No Information Found”.

How can I inspect individual nodes and zones on the surface to see what the values are for this new variable V_perp_mag?

Thanks, Greg

Already handled, sorry for the noise see visit-dav/visit#12329
