Neumann boundary for User Defined Scalar (UDS) -- CFD Online Discussion Forums

July 5, 2017, 15:13	Neumann boundary for User Defined Scalar (UDS)	#1
vcvedant Member Vedamt Chittlangia Join Date: Feb 2016 Posts: 64 Rep Power: 9	I am writing a UDF for Lam-Bremhorst turbulence model by using two scalars for k and epsilon. I want to enforce Neumann BC at the wall for Epsilon (UDS-1) that is d{eps}/dy = 0 . Can someone help me with this? Thanks.
