 Description
-    This velocity inlet/outlet boundary condition is applied to pressure
+    This velocity inlet/outlet boundary condition is applied to velocity
     boundaries where the pressure is specified.  A zero-gradient condition is
     applied for outflow (as defined by the flux); for inflow, the velocity
     is obtained from the flux with the specified inlet direction.
