UDF boundary condition

Hi,
I am working on UDF.One thing puzzles me about BC. I add a user-defined scalar transport equation in FLUENT. And the boundary condition of UDS is a function of the velocity. I wondering if the boundary profile will be updated every iteration or every time step? Many thanks. Jeff |

In my point of view, the boundary profile should be updated per time step when unsteady model is used. I think you should try to use the function DEFINE_ADJUST which is excuted at the beginning of each iteration.
good luck. |

The new version of FLUENT (6.1.22) has DEFINE_AT_END which updates UDF automatically at the end of each time step for unsteady and end of each iteration for steady case.
