33.14.3 Drag Monitor Dialog Box

You can use the Drag Monitor dialog box to save the convergence history of the drag coefficient on specified wall zones. See Section  26.13.3 for details about using this dialog box.

Controls

Options   selects one of the following methods for reporting the selected coefficient:

Print to Console   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 Window) after each iteration.

Window   sets the window ID in which the plot will be drawn. When ANSYS 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 dialog box to modify the attributes of the axes.

Curves...   opens the Curves dialog box to modify the attributes of the data curves.

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 ANSYS FLUENT session.

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

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), ANSYS FLUENT will compute and monitor the total force for all of the selected walls combined together.

Force Vector   contains the components of the force vector.

X,Y,Z   are the components of the force vector along which the forces will be computed.

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.

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

Clear   discards the force-monitoring data, including associated files. Each of these actions must be confirmed in a Question dialog box (see Section  2.1.6).
