About Model Inputs
The following model inputs (which are scalar or vector-field physical quantities that appear as inputs in, for example, a temperature-dependent material property) can be added to models from the Property Group window (vector fields have three components enclosed by curly braces).

Selection of Model Inputs is standard in most cases. Extra information is included in the documentation as applicable.
To define the absolute pressure for heat transfer, see the settings for the Fluid node.
To define the absolute pressure for a Fluid Flow interface, see the settings for the Fluid Properties node (described for the Laminar Flow interface).
If you have a license for a Nonisothermal Flow interface, see that documentation for further information.
