WebThe Slip option prescribes a no-penetration condition, u · n =0. It is implicitly assumed that there are no viscous effects at the slip wall and hence, no boundary layer develops. From a modeling point of view, this can be a reasonable approximation if the main effect of the wall is to prevent fluid from leaving the domain. Websome noble wall functions are given to reduce this restrain. In OpenFOAM the existing wall functions have been modi ed to ensure that they can provide the accurate result so wherever the position of the rst cell center.
