# Oriented_Slip

Syntax

  Bc No_Coverage_Flux For Momentum ([{of} SpeciesName] | [{in} MaterialPhaseName] | [{ls} {a | b | c}]) {@ | at | for | on | over} Mesh Extent Name ([Touching TouchingMeshExtent] | [Opposing OpposingMeshExtent]) = Oriented_Slip [Using Data Specification Data Spec Name] ([Vs_X = vs_x] | [Vs_Y = vs_y] | [Vs_Z = vs_z] | [Vs_Expr = vs_expr] | Beta_Normal = beta_normal | Beta_Tangent = beta_tangent)

Summary

  Oriented slip momentum flux. Essentially a sum of the Navier-Slip condition and a penalty condition for enforcing velocity in the normal direction.
