What kind of BC should be surround a heat source?
 
Hello Fluent users,

In the air, there is an energy source. The heat released will induce the air flow(natural convection). For such a case, what kind of boundary conditions should be used? ( Inflow or Outflow?)

Thanks.

In the domain away from the source you can use pressure out or pressure in boundary condition (on the faces) at ambient. This will allow air to enter or exit air depending on pressure.

Hope this meets your request!
