32.4.13 Solve/Monitors/Volume...

The Solve/Monitors/Volume... menu item opens the Volume Monitors panel.



Volume Monitors Panel


You can use the Volume Monitors panel to save the convergence history of the volume, sum, volume integral, mass integral, volume average, or mass average of a field variable on one or more cell zones. See Section  25.18.5 for details about the items below.

Volume Monitors   sets the total number of volume monitors to be defined.

Name   specifies a name for each volume monitor.

Plot   specifies whether or not to plot the data from each volume monitor in the graphics window (with the ID set under Plot Window in the Define Volume Monitor panel).

Print   specifies whether or not to print the data from each volume monitor in the text window.

Write   specifies whether or not to write the data from each volume monitor to a file (with the name specified under File Name in the Define Volume Monitor panel).

If you choose not to save the volume integration data in a file, this information will be lost when you exit the current FLUENT session.

Every   indicates the frequency at which you want to plot, print, or write the volume monitor. A default value of 1 will allow you to monitor at every Iteration or Time Step.

When   indicates whether the data should be plotted/printed/written after every Iteration or every Time Step. Time Step is a valid choice only if you are calculating unsteady flow. See Section  25.18.5 for details.

Define...   opens the Define Volume Monitor panel, in which you can define what each volume monitor is tracking.



Define Volume Monitor Panel


The Define Volume Monitor panel allows you to define what each volume monitor is tracking. See Section  25.18.5 for details about the items below.

Controls

Name   specifies the name of the monitor.

Report Type   selects the integration method used on the selected cell zones. The available report types are the same as those in the Volume Integrals panel. See Section  29.6 for details.

X Axis   specifies the $x$-axis function against which monitored data will be plotted or written. Available options are Iteration, Time Step, and Flow Time (elapsed time).

Plot Window   sets the window ID in which the plot will be drawn. When FLUENT is iterating, the active graphics window is temporarily set to this window to update the volume monitoring plot, and then returned to its previous value. Thus, the volume monitor plot can be maintained in a separate window that does not interfere with other graphical postprocessing.

Field Variable   contains a list of solution variables that can be monitored on the selected cell zones. This list will be deactivated if you select Volume as the Report Type.

Phase   contains a list of all of the phases in the problem that you have defined. This is available when the VOF, mixture, or Eulerian multiphase model is enabled.

Cell Zones   contains a selectable list of the current cell zones.

File Name   specifies the name of the file to which the volume data is written (if you have enabled the Write option for this monitor in the Volume Monitors panel).

Curves...   opens the Curves panel to modify the attributes of the data curves.

Axes...   opens the Axes panel to modify the attributes of the axes.
