Average Static Pressure : Over Outlet/Radial equilibrium
 

- By way of explanation for this condition, the CFX-pre user’s guide gives the formula following :



P(ip) = Paverage(user) + (P(n) - Paverage(n))
where P(ip) is the imposed pressure at each integration point.


I don’t understand what represent the local nodal value P(n) and the average outlet boundary pressure Paverage(n) ?


Is P(n) the value at the center of control volume ? And what is the difference between Paverage(user) and Paverage(n) ?


- For the radial equilibrium condition, I don’t see where I can specified the pressure for the radial reference position ?
