Flow Convergence - Absolute Pressure 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 absolute pressure converges over the selected region.Absolute DifferenceStops the analysis when the absolute difference of the average absolute pressure, between two consecutive iterations, is less than the value specified in the Absolute Pressure box.Relative DifferenceStops the analysis when the relative difference of the average absolute pressure, between two consecutive iterations, is less than the value specified in the Absolute Pressure (%) box.Upper LimitStops the analysis when the computed average absolute pressure is greater than the value specified in the Absolute Pressure box.Lower LimitStops the analysis when the computed average absolute pressure is less than the value specified in the Absolute Pressure box.
Averaging Method
Method Specifies the averaging method that the flow solver uses to compute a single value for the absolute pressure over the selected region. The flow solver uses this value to determine if the analysis is converged.RMSComputes the root mean square (RMS) of the absolute pressure value over the selected region.Maximum ValueRetrieves the maximum value of the absolute pressure over the selected region.Minimum ValueRetrieves the minimum value of the absolute pressure over the selected region.Algebraic Average ValueComputes the algebraic average absolute pressure value over the selected region.Volumetric Average ValueComputes the volumetric average absolute pressure value over the selected region.
Magnitude
Absolute Pressure Sets the target absolute pressure convergence value that the flow solver uses to stop the analysis when the computed absolute pressure reaches the specified target value.Note: When you choose Relative Difference as the stopping criteria, you set the target absolute pressure as a percentage value.
