Dear all
pleas give me your suggestion about defining the two boundary condition at the different time for simulation heat transfer: first time= 0-15s use temperature = 150C, and then time= 15-30s use 91C . the output that I want to look are the outlet temperature of each inlet boundary condition. |

You can easily to this by means of a UDF. You can take a look in the UDF Manual, and use the DEFINE_PROFILE subroutine, in which you can base the value on the time. Good luck!

See a very recent post for examples on how to do (simple) time-varying inlets:
