how to give boundary conditions( primitive boundary field)
 
hi,
i am doing acoustic analysis of a combustion chamber. i have three differential equations relating acoustic pressure, velocity and density (got by mass, momentum and energy equations after deducting from steady state equations, the actual equations).
now i have to solve these equation using openfoam with appropriate boundary conditions. At the burning surface , i have a relation between normal acoustic velocity and acoustic pressure, as P-dess/V-dess=constant. How to implement this boundary condition in openfoam syntax. Please help me.
