Domain point probe in moving mesh

Hello,
I am trying to evaluate a dependent variable at a point very close to a geometric boundary that is moved using a moving mesh. I can do this by introducing an additional boundary parallel to the original one so that i can select it in postprocessing, but this makes the mesh extremely fine in this region.
I also tried adding only a single point in the geometry, but when i select it in a point graph, I get the error:
Failed to evaluate operator. - Operator: mean - Geometry: geom1 - Point: 11 Mean operator requires a meshed adjacent entity of higher dimension when evaluated on points and edges. Failed to evaluate expression. - Expression: mean(comp1.Bz)
My question is: Is there any way to evaluate at a point in a geometry that is moving without introducing additional mesh elements, such as is done with the Domain Point Probe node? The Domain Point probe would be ideal, but it seems that it is not possible to define time dependent coordinates for the point.
Thank you
Alex

Nevermind, this did the trick:

Alex,
have you tried a cut point dataset?

Hi Edgar,
I have tried a cut point dataset, but it seems like having time-dependent coordinates outputs only the last time coordinate for some reason. The general extrusion seems to do the trick well.
Thanks,
Alex
