18.2.5. Plot Options Tab

The Plot Options tab enables you to create graphics to display scalar and vector values at injection regions, as detailed in the following sections:

18.2.5.1. Color by Parameter Value

Selecting this option and choosing a variable draws injection region symbols colored by the selected variable. The available variables depend on the settings on the Injection Details and Fluid Values tabs, as applicable. A legend appears by default showing the variable used for coloring the injection region symbols. You can turn off visibility for the legend and the plots by clearing the check box next to the object associated with your injection region in the Outline tree view.

18.2.5.2. Injection Region Vector

Selecting the Injection Region Vector option draws vectors at the injection regions, pointing in the direction specified by the Vector Components setting. The available Vector Components options are:

  • Cylindrical Hole Direction

    The Cylindrical Hole Direction option is available when, on the Injection Details tab, Injection Model > Option is set to Cylindrical Hole.

    Vectors are properly aligned with the cylindrical holes, taking into account all of the Hole Direction settings (see Hole Direction).

    If, on the Injection Details tab, the Hole Direction specification makes use of the Normal to Boundary Condition option, the direction of the injection region vectors shown in CFX-Pre might differ slightly from the direction calculated by CFX-Solver, especially where surface curvature is high.

  • Injection Region Flow Direction

    The Injection Region Flow Direction option uses the Flow Direction specification (on the Injection Details tab) to determine the direction of plotted injection region vectors.

    If, on the Injection Details tab, the flow direction is specified to be normal to the boundary, the direction of the injection region vectors shown in CFX-Pre might differ slightly from the direction calculated by CFX-Solver, especially where surface curvature is high.

  • Cartesian Components and Cylindrical Components

    The Cartesian Components and Cylindrical Components options are available when vector component specifications are found in Injection Details or other settings, and use those vector component specifications to plot injection region vectors.

    Vectors are formed from grouped parameter settings that form vectors, for example a Flow Direction specification using the Cartesian Components or Cylindrical Components option.

    The specified components of these vectors are always applied (without conversion) in the local coordinate frame.

A scaling parameter is available to adjust the length of the vectors. For details, see Injection Region Vectors.
