udf language + UDMI values
 

Hey sim collegues, 1)can somebody please send/tell me a link where I could read something about the syntax of the programming language of an udf which contains an explanation for Thread *tf, or face_t f; I just have got the source file without a comprehensive documentation. 2)I think I have a problem with the implementation of the udfs. The simulation runs normally. At the end I would like to view the results of stored values in the UDMIs but the only thing I see is a zero line for all UDMIs although the simulation results in fluent seems to show some kind of trustable solution?

thanks in advance regards
