I have a geometry/mesh (see below) that has multiple surfaces on the Z face.

How do I group all of them into a sideset, without having to manually select them ? Is there a way to select all surfaces using the face normal ?
This is to apply BCs in FEM simulation.
Hi @aeromechie,
in this case you could make use of the extended parsing in the command line.
sideset 1 add surface all with z_coord = 0
This would add all surfaces with z coord = 0 to a sideset. For more selection criterias take a look into the documentation of the extended parsing syntax.

Fantastic, thanks! It worked, and I didnt know this option before
