Group
    grpWallFunctions
 
Description
    This boundary condition provides a turbulence dissipation wall function
    condition for low- and high-Reynolds number turbulent flow cases.
 
    The condition can be applied to wall boundaries, whereby it inserts near
    wall epsilon values directly into the epsilon equation to act as a
    constraint.
 
    The model operates in two modes, based on the computed laminar-to-turbulent
    switch-over y+ value derived from kappa and E.
