2-d problem BOUNDARIES IN prostar
 

IN 2-D DIMENSION, THE BOUNDARIES HOW I CAN DEFINE THEM WITHOUT THE CURSOR, BUT ONLY WITH THE EDGES, WHICH ARE NOT SURFACES IN 2-D BUT SIMPLE LINES???

STAR doesn't run 2D cases in this way: for a 2D simulation you require a 3D mesh, but there is only one cell in the third dimension. Change your mesh and all your boundaries will have a face, not just a line.
