Initial Values
This node adds an initial value for the relative humidity 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.
Initial Values
For User defined, enter a value or expression for the initial value of the Relative humidity . The default value is 0.5. Else, select an Ambient relative humidity defined in an Ambient Properties node under Definitions.
