  Hi All,
  I have a question about Define_Exchange_Property UDF. If I specified my mass transfer rate, i.e; m_dot(pq) using a UDF, do I need to include it in my define_Exchange_property UDF or fluent automatically adds it. I am referring to the terms in the red box. I want to know, if I am only required to write a UDF for R_pq and fluent will automatically add the terms in the red box for me or I have to include it myself. Thanks.

  New habit to mention the active Ansys members on any new topic..
  Anyway:
  If you define the mass transfer rate via DEFINE_MASS_TRANSFER or the linearized version of it: you do not need to do anything else!
