Please, how to set boundary condtions in computational domain for structured O-grid. The flow about symetric airfoil is incompressible, laminar and viscous.

far-field or characteristics on the external O body on the internal O periodicity in the cut

thanks Mar; Do you have more details about periodicity in the cut; do you mean that: u(1,j)=u(imax,j) and v(1,j)=v(imax,j) for j=1 to jmax

yes if your cut is along j, as usual.

The condition must be applied for all the variables also termodinamic (pressure, energy..)

I'm in the case of 2D, incompressible viscous flow attempting to find the position of separation on the airfoil for a given Reynolds number (5x10e3). I'm using finite volumes method to discretize the mathematical model in computational domain. So please what may i set for the coefficients of discretized algebraic equation: Ap.(PHI)p=Ae.(PHI)e+Aw.(PHI)w+An.(PHI)n+As.(PHI)s+ S for boundary conditions?
