### 6.2.1. Setting up Monitors to Check Results

While setting up an analysis that involves the Time Transformation or Fourier Transformation model, you should add some monitor points for diagnostic purposes. The monitor points should be placed at strategic locations, and should monitor variables that are expected to have periodic fluctuating values. During or after the run, you can check the monitor point values in CFX-Solver Manager to ensure that:

- Each monitored variable value fluctuates in a repeating pattern (periodicity).

- The period of such fluctuations correspond to the blade passing frequency of the neighboring row.

For the case of a flutter analysis, you can set up aerodynamic damping monitors to check whether vibration is damped or undamped (for the frequency being studied). For details on aerodynamic damping monitors, see Case 3: Blade Flutter and Aerodynamic Damping: Frame Overview in the CFX-Pre User's Guide.
