Output Window

The Output window is the primary vehicle for communicating the results of an analysis in text form (see Figure 1). The Output window follows the same general window organization as the Model Data window.

When a model is submitted to the Solver, the Solution Progress window appears. After the solution is obtained, you can view the results in the Output window by clicking the View Output button.

If the information in the Output window is not in the desired format, you can choose Output Control from the Tools menu (or Toolbar) to modify the format. The Output Control window lets you specify the parameters, their units, and the order of their display in the Output window.

The Output Print Content window available on the Tools menu (or Toolbar) lets you specify the content to include in the printed Output report and select the font to be used.

The Sort window opened from the Arrange menu (or toolbar) offers the ability to sort the Pipe Results or Junction Results tables according to the values in any of the columns.

The Transfer Results to Initial Guess feature on the Edit menu (and Toolbar) sets all pipe and junction initial steady-state flows and pressures equal to the converged results, which causes future runs to converge much faster.

You can view the input data for individual pipes or junctions directly from the Output window in one of two ways. First, if you press down the right mouse button on the pipe or junction number in the far left column of the table you will see the Inspection window. Second, if you double-click the pipe or junction number you will open the Properties window in read-only form where you can review input in detail.

General, Pipe, and Junction section display sizes can be changed by the user by clicking and dragging the bars between each section to re-size them. Each section can also be hidden by clicking the arrow in the upper left of each section.

You can use the zoom feature in the lower right hand corner of the Output window to re-size the text displayed on screen

    • Create Design Alert -Create a Design Alert related to the selected object and value.

    • Copy Selected Cell Data - Copies the value of the cell to the clipboard.

Output Window Updates

Whenever you change the input model, all output windows are erased. This prevents you from changing your input model, forgetting to rerun it, and mistaking the previous Output window for the current model's results.

Steady Flow Results

Figure 2 shows the steady flow results in tables for pipes and junctions as specified in the Output Control window. Details of the steady state results at each pipe calculation station can be viewed on the Axial Points tab of the Pipes section.

Figure 2: The Output window shows steady flow results in the Pipes and Axial Points tables and the various junction tables. Transient data is shown on the transient tabs.

Transient Flow Results for Pipes

You can review the transient results for any pipe station for any time which was saved to file as specified in the Simulation Duration panel. These results are shown in the Output window Transient Output table (Figure 3)

Figure 3 shows the transient flow results at the initial time step (which is equal to zero here). The columns of data shown in Figure 3 are specified in the Output Control window. Using the Time Slider will change what time step results are displayed.

Note that the pipe stations shown are those saved to the output file.

Figure 3: The Transient Output table in the Output window shows output results for pipe stations and at specified times

Transient Max/Min Results for Pipes

You can review the maximum and minimum transient results for all pipes for all times. The data shown is not dependent on which pipe stations or time steps were saved to file. Figure 4 shows the Transient Max/Min table in the Output window. The parameters that are shown are the same as those specified in Output Control. However, there are four columns for each parameter. The four columns show the maximum and minimum values for the parameter, and the times at which each maximum and minimum occurs in the pipe.

Figure 4: The Transient Max/Min table details the maximum and minimum values for the entire simulation

Summary Max/Min Results

There is a summary version of the Transient Max/Min table, which is the default view. The version shown in Figure 4 is what is called the Detailed version. You can switch between detailed and summary views by selecting the option on the Output Control, Format & Action tab.

The summary version shows only maximum and minimum values for the entire pipe, as opposed to each pipe station. The summary also shows the pipe station that is the overall maximum or minimum for the pipe. Therefore, for each Output Control transient parameter there are six columns in the summary version of the Transient Max/Min table. See Figure 5 for an example.

Figure 5: Summary version of the Transient Max/Min table

Transient Event Messages

When events occur at junctions during the transient simulation, a log of all events is displayed in the two Event Message lists. In the first list events are sorted by junction number. In the second list they are sorted by time. The list includes when check valves close (and re-open), relief valves open, control valves lose control (and regain it), as well as all standard event transients.

Results Diagrams

Results diagrams are available for steady state compressor/fan results (see Figure 6). These diagrams allow you display the information in a more intuitive manner, copy the image of the diagram to your clipboard, or print the diagram. The option to show the results diagram can be found in the compressor/fan summary tab.

Printing and Exporting

Data in the Output window can be:

  • Copied to the clipboard

  • Saved to a formatted text file

  • Exported to a delimited file suitable for direct importing into spreadsheet software

  • Exported directly to Excel

  • Saved directly to an Adobe PDF file

  • Sent to the printer

The printed and Adobe PDF output follows the same flexible, organized, and accessible format as the Output window itself.
