OK.

Warning: with the latest version (I've uploaded 1.53.1 yesterday) you
should either use that "trick" or specify non-zero region numbers in
the Layers commands, but not both (cf. attached file).

Sure: newp returns the number of the next available *geometry*
point---not the next mesh node.

You already have that info in the mesh file---no need to add Physical
Points. Just loop through all the elements and get the nodes of the
elements that belong to the physical groups you're interested in. That's
really how the code is supposed to work.

Best,

Christophe
