To obtain a report (for selected wall zones) of forces along a specified vector or moments about a specified center, use the Force Reports panel (Figure 29.3.2).
The steps for generating the report are as follows:
A shortcut that may be useful if you have a large number of wall zones is to specify a Wall Name Pattern and click Match to select wall zones with names that match the specified pattern. For example, if you specify out*, all walls whose names begin with out (e.g., outer-wall-top, outside-wall) will be selected automatically. If they are all selected already, they will be deselected. If you specify out?, all walls whose names consist of out followed by a single character will be selected (or deselected, if they are all selected already).
If Forces has been selected under Options, the console window will display the pressure force, viscous force (if appropriate), total forces, pressure coefficient, viscous coefficient, and total coefficients for each selected wall zones.
If Moments has been selected, the pressure moments, viscous moments (if appropriate), total moments, pressure coefficient, viscous coefficient and total coefficients for each selected wall zones will be displayed. Additionally, the net values of the coefficients and the forces or moments for all selected wall zones will be printed at the end of the report. See Section 29.3.1 for details about computing forces and moments.
If Center of Pressure has been selected, then FLUENT prints out the coordinates about which the moment is zero.
To demonstrate how you would generate and interpret the center of pressure report, consider Figure 29.3.3 which shows an airfoil of chord length 1 m.
