[Gmsh] Restrict Field

[Karin&NiKo]

Dear Gmsh gurus,

I would like to assign some size fields depending on some mathematical
expressions *and* depending also on  regions.
To this end, I used the Restrict field but my use seems to be
inappropriate. Unfortunately, there are no test or example.

Could you please provide me with some help?

My example is attached to this email.

Best regards,
NiKo
