+
+Description
+    This boundary condition provides a turbulence kinetic energy wall function
+    condition for low- and high-Reynolds number turbulent flow cases.
+
+    The model operates in two modes, based on the computed laminar-to-turbulent
+    switch-over y+ value derived from kappa and E.
