radix New Member Raditya Wiranegara Join Date: Aug 2009 Location: United Kingdom Posts: 22 Rep Power: 17	Dear All, I'm thinking of replacing the production term in Spalart-Allmaras with a modified one via UDF. For what I have read, there is no way to access the term via UDF (please correct me if this is wrong). Therefore, is it possible if I used the user-defined source term to manually delete the original production term (by mimicking the exact formulation with opposite sign) and add the modified one using UDF? Many thanks, Radit
