Problem with meshing and hight pressure setting

mameri

Hi, I am using CFX to simulate combustion at hight pressure. First, I don't know how to set the chamber pressure at 0.9 Mpa in CFXPre. Second, when i use extrude in Advenced meshing (the chamber is axisymetric for that i take 2 or 3 deg to have 2D calculations), after getting mesh when i import it in the CFXpre the boundary conditions vanishes. Thank You.
