Create an XY Plot

• On the ribbon, click Flow Simulation > Results > Insert > XY Plot.

• On the toolbars, click XY Plot on the Flow Simulation Results Features toolbar.

• In the menu, select Tools > Flow Simulation > Results > Insert > XY Plot.

• In the Flow Simulation analysis tree, right-click the XY Plots item and select Insert.

In the graphics area select edges or in the flyout FeatureManager design tree select sketches or curves to see how a parameter changes along the selected items.

These lines appear in the Sketches, Curves, Edges  list.

To remove the selected line from this list, select it in the list and press Delete or right-click it and select Delete.

• Coordinate System . Allows you to select a Coordinate System  in which the X, Y and Z components of vector parameters are calculated. By default, the Global Coordinate System is selected.

  Tip

  You can replace the default coordinate system by selecting your coordinate system in the flyout FeatureManager design tree.

  To create a coordinate system, click Insert > Reference Geometry > Coordinate System.

• Abscissa . Allows you to select the chart abscissa.

  • Length. The chart abscissa is the length of the sketch line, edge or curve.

  • Model X, Y, Z. The chart abscissa is a coordinate of the Allows you to select the chart abscissa.

  • Height. The chart abscissa is the height of the sketch or curve.

  • Sketch X, Y, Z. The chart abscissa is a coordinate of a sketch coordinate system.

    Note:

    When creating a 3D sketch, you can use sketch relative to any reference coordinate system. For 2D-sketches, the global coordinate system is used.

• Moving selection. When checked, the chart abscissa moves with the rotating region.

  Note:

  This option is available if you have selected the Local region(s) (Sliding) option on the Analysis Type tab of the General Settings or Wizard dialog (see “Rotation” for details).

To change the list of parameters available for selection, click More Parameters (see “Customize Parameter List” for details).

• Geometry Resolution . Controls how well the curve is approximated with linear segments.

  A higher resolution setting results in slower XY plot creation but a more accurate curve’s form is created. For a line it is enough to set the minimum geometry resolution (2 endpoints). For complex curves a greater resolution is recommended.

  Table 1. Geometry resolution.

  The line is accurately defined by 2 endpoints:	The curve is approximated with 5 points:

  Each linear segment is further subdivided into a number of sub-segments depending on the calculation mesh, model geometry and the flow field.

• Click Evenly Distribute Output Points  and specify Number of Points to output parameter values at the specified number of the curve’s points evenly distributed along the curve.

• Use CAD geometry. By default, Flow Simulation shows the original model while displaying results. Depending on how exactly the model is resolved by the computational mesh, the geometry actually used in the calculation can differ slightly from the original model geometry.

  Clear this option to use the Flow Simulation-interpreted geometry for the plot.

• Interpolate. By default, Flow Simulation displays the parameter distribution so that values determined in the cell centers are interpolated through the computational mesh cells.

  Clear this option to switch off the interpolation and accelerate operations related to displaying results. In this case parameter values in the cell centers will be displayed without any interpolation between cells.

• Merge connected lines. Allows to merge the connected sketch segments into a single line.

• Flip origin. Allows you to change the abscissa direction, if the Length of the line is selected as the chart abscissa.

• Offset (off by default).

  Note:

  This option is only applicable for the XY plots located on the solid-fluid interface (wall).

  If the Offset option is selected and the Interpolate option is not selected, Flow Simulation takes the parameter values in the centers of fluid volumes of Solid-Fluid Boundary Cells, i.e. in the first fluid volumes from the wall. If the Interpolate option is selected, the parameter values from centers of fluid volumes are interpolated to the location of the XY plot by the standard interpolation procedure.

  If the Offset option is not selected, the XY plot shows the values of parameters at the wall (e.g. the velocity at the surface of a non-moving wall is always equal to zero).

• Excel Workbook format . Allows to select the file format that you know you can open.

• Click Show to calculate the parameters and create a chart.

  The calculated parameters values are displayed as charts on the pane at the bottom of the screen. Each parameter is plotted on a separate chart (see “XY Plot Pane” for details).

• Click Export to Excel to calculate the parameters and export data into Microsoft Excel.

  Note:

  If you want to export data of the group of XY plots into Microsoft Excel at once, in the Flow Simulation analysis tree right-click the XY Plots icon and select Export All to Excel.
