After performing an aerodynamic analysis in Fluent, the drag coefficient, lift coefficient, pressure coefficient, lift and so on can be analyzed. Resistance and lift coefficients must set before calculating (Solve->Monitor->Create). Make sure to correctly set the reference pressure, projected area and speed values in Report->Reference Values. The pressure coefficient can be displayed in a contour plot (Display->Contours) by selecting Pressure and Pressure coefficient for the variable. It can also be plotted with Plot->XY Plot. Drag and lift can be integrated from Report->Force. Displaying the drag and lift of a wall cell requires custom field function (Define->Custom Field Function) to be created with Pressure * function of projected area in drag or lift direction. It can then be displayed in a contour diagram. Note: The projected area of the wall cell in the x, y, z directions use the mesh variables X Surface Area, Y Surface Area, and Z Surface Area.
