Probing several boundaries

Please login with a confirmed email address before reporting spam

Dear community,

I have a cuboid with laminar inlet. Now I want to observe the development of pressure and velocity on one of my upper surface. To implement that I created a workplane in Geometry with some rectangles (see the attached picture). Now I wanted to set the rectangles as probes to see the difference from the first to the last one. I selected several rectangles one at a time (boundary selection) with pressure and velocity as expression. But I get "NaN" as result. When I checked the laminar flow conditions the probe rectangles are marked as "not applicable, so I guess that´s why I don´t get a result but NaN.

Should I set the probes in the different way?
How can I mark several probes without creating an own probe for each rectangle (e.g. by duplicating the first probe)?

I would appreciate any help!
Regards, Kristina
