For teaching and explanatory purposes it is helpful to use the concept of an inviscid fluid or an ideal fluid which offers no resistance to shearing and so is not viscous. Source: Internet
At angles of attack above stall, inviscid calculations do not predict that stall has happened, and as a result they grossly overestimate the lift. Source: Internet
