Hi,
Could anyone tell me how to set the inlet velocity boundary with a variable inflow velocity(ex.the developed flow)? There is only the constant item on the menu. Thanks a lot! Lili |

You have to use a UDF if your BC is very complex, but I hope you like programming in a C based language.
If you just have a time based or periodic profile that does not change as a function of the geometry (IE like in the radial direction) you can use a profile. Define an SI based profile as a function of time, read it from the TUI using the File Read-Transient-Table, then when you go to the Velocity Inlet BC pulldown arrow, you will be able to select your profile rather than the constant. The Fluent Users Center has more details - get yourself a password if you don't have one already. John |
