VBM shows 15 VBM data fields for each computational cell in the entire domain. The VBM variables are cell-based and will not display correctly as node variables. They are calculated only in the cells attached to the actuator disks. The labels of the VBM parameters are listed in Table 18.2: VBM Field Variables.
