This node adds an initial value for the temperature that can serve as an initial condition for a transient simulation or as an initial guess for a nonlinear solver. In addition to the default
Initial Values node always present in the interface, you can add more
Initial Values nodes if needed.
For User defined, enter a value or expression for the initial value of the
Temperature T (SI unit: K). The default value is approximately room temperature, 293.15 K (20ºC). Else, select an
Ambient temperature defined in an
Ambient Properties node under
Definitions.
