An important feature of the graphical output visualization is the option to present multiple steady state or transient series for a specific parameter in one graph using breaks.

 

Let's take a look at the effect of Mach number on the transient performance as specified in Specifying transient simulation input.

1.If the transient table is not visible, select Results|Transient|Table in the model window. If the transient data is cleared, perform the actions as specified in Running transient simulations.
2.Click the 'append break button' of the table window toolbar to append a break line.

The graph window will automatically interpret the break lines as curve separators.

3.Click Amb.Cond. above the project tree.
4.Click the Off-design conditions tab sheet.
5.Change the Air Speed Mach value to 0.4 and click OK.
6.Run the model to perform the transient calculation (set time to 0, click OK in the set start time window and Yes in the stabilize window).
7.Click Graph in the transient table window.

The graph is displayed, with 2 curves for Mach 0.0 (blue) and 0.4 (black dashed).

8.Optionally change axis variables for similar graphs with other output parameters.
9.Repeat the process for similar graphs with other input parameters.

For example, study the effects of height (zp) on performance.

 

Note: It is required to "reset" the operating point of the model between the steady state series or transient simulations. Make sure extra data lines resulting from any steady state or design point calculations are deleted to prevent spoiling of the graph.
