Flow Convergence - Enthalpy dialog box (Flow/ESC/Multiphysics)

Modeling Object
Name Sets a name for the modeling object.
Label Sets a unique numeric identifier for the modeling object.
Properties
Description Sets a description for the modeling object.Click Description to set the description in an editor box.
Stopping Criteria
Criteria Specifies the stopping criteria that the flow solver uses to determine if the enthalpy converges over the selected region.Absolute DifferenceStops the analysis when the absolute difference of the average enthalpy, between two consecutive iterations, is less than the value specified in the Enthalpy box.Relative DifferenceStops the analysis when the relative difference of the average enthalpy, between two consecutive iterations, is less than the value specified in the Enthalpy (%) box.Upper LimitStops the analysis when the computed average enthalpy is greater than the value specified in the Enthalpy box.Lower LimitStops the analysis when the computed average enthalpy is less than the value specified in the Enthalpy box.
Averaging Method
Method Specifies the averaging method that the flow solver uses to compute a single value for the enthalpy over the selected region. The flow solver uses this value to determine if the analysis is converged.Absolute Maximum ValueRetrieves the absolute maximum enthalpy value over the selected region.Maximum ValueRetrieves the maximum enthalpy value over the selected region.Absolute Minimum ValueRetrieves the absolute minimum enthalpy value over the selected region.Minimum ValueRetrieves the minimum enthalpy value over the selected region.Algebraic Average ValueComputes the algebraic average enthalpy value over the selected region.Volumetric Average ValueComputes the volumetric average enthalpy value over the selected region.
Magnitude
Enthalpy Sets the target enthalpy convergence value that the flow solver uses to stop the analysis when the computed enthalpy reaches the specified target value.Note: When you choose Relative Difference as the stopping criteria, you set the target enthalpy as a percentage value.
