Slip and no-slip boundary condition
 
Hello All,

Is there any tutorial available where slip boundary condition has been utilized?

I wanted to understand the physics and its implementation.

Thank you

A symmetry boundary condition could be used as "slip condition" depending on a code's implementation.

While the no-slip BC corresponds to the physics of a real fluid over a wall, the slip condition corresponds to an idealized mathematical model of an inviscid fluid. Differences in the BC correspond to different mathematical character of the equations (parabolic/elliptic for real fluid and hyperbolic for inviscid). I suggesto to see first these differences in a good textbook of basic fluid dynamics, then you can see the issues in the numerical solution.
