WebThe meaning of BOUNDARY CONDITION is a condition which a quantity that varies throughout a given space or enclosure must fulfill at every point on the boundary of that … WebA periodic boundary condition is used in the spanwise direction, in order to avoid any three dimensional (in the mean) effects. Free slip boundary conditions are applied for y = ± Ly / 2. A zero-stress like condition is used at the outflow, coupled to a buffer zone to prevent spurious reflexions.
