By default, VBM writes the Rotor_xx_Loads.csv files for each rotor xx to report the VBM global outputs. These outputs include the force, moment and power on the rotor disk, as defined in Table 18.3: VBM Global Outputs for Each Rotor, considering the local coordinates shown in Figure 18.1: Rotor Disks Schematic. In this table, , and repesents the local coordinates and stands for the radius of a facet cell. The components of the time-averaged force on the facet cell are denoted as , , and represents the tangential force on the facet cell. Within this table, is the rotor speed, is the rotor disk area, is the rotor radius and is the rotational speed of the rotor. Throughout the simulation, you have the option of monitoring, printing, writing and/or plotting these global solutions for any rotor using VBM report definitions. To set up VBM reports using the VBM Report Definition dialog box, go to:

 Solution → Reports → Definitions  New... → VBM Report → Rotor...

From there, you can choose one of the available report type options. Additionally, you can set the Output Type to Coefficient if required.

It's important to define VBM reports individually if you intend to have multiple report definitions printed to the Console, written to a file or plotted in the Graphics window. This is useful for monitoring convergence and recording time histories.
