Use the Surface Temperature node to define the surface temperature at the boundary. For nonisothermal models, additional Surface Temperature features can be added to the model to define different temperatures on different surfaces. The temperature can also be computed by a second coupled physics interface (for example, a Heat Transfer in Solids interface).

By default the Temperature T (SI unit: K) is User defined. The default is 293.15 K. If additional physics interfaces (such as a Heat Transfer in Solids interface) are available which compute the temperature, the output of these physics interfaces can be selected.
