Generally, the no-slip condition should be satisfied on the solid wall. For hydrophobic materials, however, partial slip on the wall is allowed. This merge request added an implementation of a partial slip boundary condition with a constant slip length.
This merge request is also a preparation for the wall model branch !1266
The partial-slipe model is set as a Dirichlet-type boundary condition, where the boundary velocity equals the multiplication of the slip length and wall-normal velocity gradient. The slip length is specified in the boundary condition.
A new calss
SlipWallBoundaryCondition is created to evaluate the slip velocity. A relaxation iteration is added in the function
VelocityCorrectionScheme::v_SolveViscous to enforce the partial-slip boundary condition.
