While in many configurations, the Temperature and Inflow features describe similar conditions and lead to similar simulation results, there are a number of configurations (especially for slow flow and small dimensions) where the conductive effects are not dominated by the advective effects and where the Inflow boundary condition usually leads to a temperature profile that is closer to the reality than a Temperature boundary condition. In these cases, a Temperature boundary condition may enforce an erroneous temperature value that induces large heat fluxes that are not realistic.
