1. An airfoil assembly comprising:
a platform having an upstream edge, a downstream edge and a surface extending therebetween, with at least a portion of the surface extending circumferentially along a surface baseline defined by a constant radius;
an airfoil extending from the platform and having an outer wall extending between a leading edge and a trailing edge and between a root and a tip defining a span-wise direction, the outer wall defining a pressure side and a suction side;
a fence along the outer wall and defining a raised potion of the outer wall, the fence following a local contour of the surface; and
at least one of:
a projection located along the platform and extending along the outer wall, the projection extending radially outward from the surface baseline; or
a valley located along the platform and defining a depression formed along the surface, the valley extending radially inward from the surface baseline to a maximum depth;
wherein at least a portion of the fence follows the local contour defined by at least one of the projection or the valley.
