The Monitor tab for the Output Control object contains settings that specify monitor output. The following types of information can be monitored as a solution proceeds:
Primitive or derived solution variables.
Fluid Properties.
Expressions
When monitoring expressions, the expression must evaluate to a single number.
For details, see Working with Monitors.
This check box determines whether or not monitor data is generated as a solution proceeds. If it is selected, the following settings are available:
(applies only for transient cases)
This check box determines whether or not monitor data is output within coefficient (inner) loops. Regardless of the setting, data will be output for each timestep.
Full
Mass, Momentum, and other balances are written to the solver monitor file.
None
Full
Forces and moments on wall boundaries are written to the solver monitor file.
None
Full
Flow and source totals (integrals over boundaries) are written to the solver monitor file.
None
Full
If Lagrangian Particle Tracking information is included in the simulation, force, momentum, and source data for particles are written to the solver monitor file.
None
This check box determines whether or not the device efficiency can be monitored in the Solver Manager. If it is selected, the following information has to be specified:
This list box is used to select monitor objects for editing or deletion. Monitor objects can be created or deleted with the icons that appear beside the list box.
Cartesian Coordinates
Monitor point data includes variable values at the node closest to the specified point. A crosshair will be displayed in the viewer to indicate the monitored node.
Expression
An expression is monitored.
(applies only when Option is set to Cartesian Coordinates)
Select the variable(s) to monitor.
Hold the <Ctrl> key when clicking to select multiple variables.
(applies only when Option is set to Cartesian Coordinates)
Enter coordinates for the point location to monitor.
After you click a coordinate entry area, they turn yellow to show that you are in Picking mode. You can then select locations from the viewer using the mouse. To manipulate the object in the viewer while in Picking mode, use the viewer icons (rotate, pan, zoom) in the toolbar. You can end Picking mode by changing the keyboard focus (by clicking in another field, for example).
(applies only when Option is set to Expression)
Enter a CEL expression that evaluates to a single number which is to be monitored.
This check box determines whether the coordinate frame used to interpret the specified Cartesian coordinates will be specified
or left at the default of Coord 0.
Set the coordinate frame used to interpret the specified Cartesian coordinates appearing in an expression, as applicable. For details, see Coordinate Frames.
(applies only when using the Discrete Transfer or Monte Carlo thermal radiation model)
A radiometer is a user defined point in space which monitors the irradiation heat flux (not incident radiation) arriving at the required location. The user specification involves much more than just the location of the sensor, as it also requires the viewing direction, its temperature and some numerical controls for each particular sensor.
By default, radiometers are ideal and the efficiency factor is 1.
A cross-hair symbol is used to denote the location in the viewer of each sensor.
This list box is used to select Radiometer objects for editing or deletion. Radiometer objects can be created or deleted with the icons that appear beside the list box.
Enter Cartesian coordinates that describe the location of the radiometer. These coordinates are interpreted in the coordinate frame associated with the radiometer. For details, see Coordinate Frames. For details, see Coordinate Frames.
Enter the number of rays used for ray tracing from the radiometer.
This check box determines whether the coordinate frame used to interpret the location and direction specifications of the
radiometer will be specified or left at the default of Coord 0.
Select a coordinate frame to interpret location and direction specifications of the radiometer. For details, see Coordinate Frames. For details, see Coordinate Frames.
This check box determines whether the diagnostic output level will be specified or left at the default of 0.
Enter a number greater than zero. The ANSYS CFX-Solver will write the ray traces to a series of polylines in a .csv file which can be visualized in ANSYS CFX-Post. This can be used to determine if the number of quadrature points is optimal.
(applies only when Monitor Options check box: Radiometer: [Radiometer Name]: Direction: Option is set to Cartesian Components)
Enter a numerical quantity or CEL expression for each Cartesian component of a direction vector that represents the orientation of the radiometer.
