REPL vertices error.

Samir

Hi; I am using an imported mesh with vertices defined (in Gambit) in to prostar. The symmetry planes seem to be defined, but when I try to select cell faces for inlet boundary conditions it gives me an error saying vertex ,, not defined. Questions: 1.How do I define all vertices? 2.How do I select boundary conditions based on vertices rather than selecting every face. Kindly give me an hint. Thank you in advance, Samir. have a good day...
