32.4.12 Solve/Monitors/Surface...

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



Surface Monitors Panel


You can use the Surface Monitors panel to save the convergence history of the average, integral, flow rate, or mass average (among other quantities) of a field variable on one or more surfaces. See Section  25.18.4 for details about the items below.

Surface Monitors   sets the total number of surface monitors to be defined.

Name   specifies a name for each surface monitor.

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

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

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

If you choose not to save the surface 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 surface 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  25.18.4 for details.

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



Define Surface Monitor Panel


The Define Surface Monitor panel allows you to define what each surface monitor is tracking. See Section  25.18.4 for details about the items below.

Controls

Name   specifies the name of the monitor.

Report Type   selects the integration method used on the selected surfaces. The available report types are the same as those in the Surface Integrals panel. See Section  29.5 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 surface monitoring plot, and then returned to its previous value. Thus, the surface monitor plot can be maintained in a separate window that does not interfere with other graphical postprocessing.

Report of   contains a list of solution variables that can be monitored on the selected surfaces. This list will be deactivated if you select Mass Flow Rate 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.

Surfaces   contains a selectable list of the current surfaces.

File Name   specifies the name of the file to which the surface data is written (if you have enabled the Write option for this monitor in the Surface 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.
