32.4.11 Solve/Monitors/Force...

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



Force Monitors Panel


You can use the Force Monitors panel to save the convergence history of the drag, lift, and moment coefficients on specified wall zones. See Section  25.18.3 for details about using this panel.

Controls

Options   selects one of the following methods for reporting the selected coefficient:
Print   specifies whether or not to print the selected coefficient in the console window after each iteration.

Plot   specifies whether or not to plot the selected coefficient in the graphics window (with the ID set in Plot Window) after each iteration.

Write   specifies whether or not to write the selected coefficient data to a file (with the name in File Name) after each iteration.

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

Per Zone   specifies whether or not the forces or moments for multiple walls should be monitored on each wall separately. When this option is turned off (the default), FLUENT will compute and monitor the total force or moment for all of the selected walls combined together.

Coefficient   selects the active force or moment coefficient in the panel. You may choose Drag, Lift, and/or a component of the Moment vector. You can monitor one, two, or all three of the coefficients while iterating. When you select the required coefficient, the current (or default) panel settings are shown for that coefficient. Clicking Apply will save the current panel settings for the selected coefficient.

Wall Zones   contains a selectable list of wall zones on which the selected coefficient is computed. If you are monitoring more than one coefficient, the list of selected wall zones is often the same for each coefficient. If you want, however, you can have each coefficient computed on a different list of zones.

Force Vector   contains the components of the force vector. This label is visible only if Drag or Lift is selected in the Coefficient drop-down list.
X,Y,Z   are the components of the force vector along which the forces will be computed.

Moment Center   contains the Cartesian coordinates of the moment center. This label is visible only if Moment is selected in the Coefficient drop-down list.
X,Y,Z   are the Cartesian coordinates of the moment center about which moments will be computed.

About   selects the component of the moment vector to be monitored. For two-dimensional flows, only the moment vector about the $z$-coordinate axis exists. Presently, you can monitor only one component of the moment vector at a time. This control is active only if Moment is selected in the Coefficient drop-down list.

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 force monitoring plots, and then returned to its previous value. Thus, the force coefficient plots can be maintained in separate windows that do not interfere with other graphical postprocessing.

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

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

File Name   specifies the name of the file to which the force data is written (if you are using the Write option).

Plot   displays an XY plot of the convergence history of the selected force or moment coefficient.

Clear   discards the force-monitoring data, including associated files. Each of these actions must be confirmed in a Question dialog box.
