      A Viscous analysis involves a solution of the full Navier-Stokes equations whereas an Inviscid analysis ignores all viscous effects. With the Inviscid option, the default wall boundary condition, even if it is not displayed, is free slip: -Zero wall shear stress -Zero normal wall velocity: no penetration -Non-zero tangential velocity as the velocity of the fluid near the wall is not retarded by wall friction effects.
