I believe the only way that you can achieve this is with a UDF. If that is the case and you have not created a UDF before then you are faced with a decision of either finding someone who will make one for you, possiable for a fee, or learning UDF programming and doing it yourself.
Check out the UDF manual for Fluent 6. |

bikash,
take a look at the following udf for varying temperature at a boundary. your udf will look similar but it will act on the source term. /************************************************** ********************/ /* unsteady.c */ /* UDF for specifying a transient velocity profile boundary condition */ /************************************************** ********************/ #include "udf.h" DEFINE_PROFILE(unsteady_temp, thread, position) { face_t f; begin_f_loop(f, thread) { real t = RP_Get_Real("flow-time"); F_PROFILE(f, thread, position) = 350. + 5.0*t; } end_f_loop(f, thread) } |
