32.7.18 Display/PDF Tables/Curves...

The Display/PDF Tables/Curves.. menu item opens the PDF Table panel.



PDF Table Panel


You can dispaly 2D plots and 3D surfaces showing the variation of species mole fraction, density, or temperature with the mean mixture fraction, mixture fraction variance, or enthalpy. See Section  15.12.3 for details about the items below.

Controls

PDF Data Type   describes the system that you are displaying.

Plot Variable   contains a drop-down list from which you can select temperature, density, or species fraction as the variable to be plotted.

Scalar Dissipation   specifies the value of the Scalar Dissipation which is available for multiple flamelets only.

Plot Type   gives you the choice of plotting a 3D surface or a slice of a 3D surface.
3D Surface   displays a 3D plot of the variation of species mole fraction, density, or temperature with the mean mixture fraction, mixture fraction variance, or enthalpy.

2D Curve on 3D Surface   consists of a 2D curve which is a slice of a 3D surface.

Options   contains options specific to the display of 3D surfaces or 2D curves on 3D surfaces.
Draw Numbers Box   enabling this option displays a wireframe box with the numerical limits in each coordinate direction. This option is available only when 3D Surface is selected.

Write To File   specifies whether you want to write the plot data to a file. This option is available only when 2D Curve on 3D Surface is selected. The Plot button changes to a Write button when this option is enabled.

Surface Parameters   contains settings where discrete independent variables are held constant and where curve parameters are defined.
Constant Value of   specifies the discrete independent variable to be held constant in the lookup table. The choices are Scaled Heat Loss/Gain, Mean Mixture Fraction, or Scaled Variance. For a two-mixture-fraction case, the Scaled Heat Loss/Gain is the only available option.

Slice by   allows you to select whether the 3D array of data points available in the look-up table will be sliced by Index or Value.

Index/Value   contains index/values and their ranges.
Index/Value   allows you to specify the discretization index or numerical value of the variable that is being held constant.

Min/Max   are the range of integer values that you are allowed to choose from or display.

Adiabatic   is the enthalpy slice index corresponding to the adiabatic case for which the enthalpy ( Scaled Heat Loss/Gain) is held constant.
Curve Parameters   allows you to specify the X-Axis Function against which the plot variable will be displayed when 2D Curve on 3D Surface is selected.
X-Axis Function   allows you to select Mean Mixture Fraction or Scaled Variance against which the plot variable will be displayed.

Constant Value of Scaled Variance/Mean Mixture Fraction   allows you to specify the type of discretization for the variable that is being held constant.
Slice by   allows you to select whether the 3D array of data points available in the look-up table will be sliced by Index or Value.

Index/Value   contains index/values and their ranges.
Index#/Value   allows you to specify the discretization index or numerical value of the variable that is being held constant for the curve parameters.

Min/Max   are the range of integer values that you are allowed to choose from or display.

Display   displays the plot variable of the 3D surface.

Plot   plots the plot variable for the 2D curve on 3D surface.

Write   opens the Select File dialog box where you will specify a name for the file containing plot data. This button appears when Write To File is enabled for the 2D Curve on 3D Surface plot type.
