Displaying results only on the selected surface inside the cavity

Hi,

I have results from OpenFOAM and I’d like to display the pressure distribution only on the surface inside the cavity (I marked it with arrow):

So I would have to extract the cells belonging to it (I assume that it’s not possible to extract their faces only, right ?). Selecting them manually wouldn’t make sense, box selection would also be difficult. Is there another way ?

All right, I handled this using the Clip filter to expose that face and then applying the “Select Cells On” selection mode to pick just one layer of elements. Finally, I used the Extract Selection filter to show the results on that extracted part of the mesh only.
