Calculating and Solving a System
To calculate and solve a system:
- Open the .pfe file for the pipe system you want to calculate in Pipe Flow Expert.
- The pipe system is displayed in the Drawing pane. In order to calculate a system’s values, the pipe system must be open in the Drawing pane.
- Click the Calculate button on the tool bar.
- The system results are calculated and the Results Log dialog is shown.
If the pipe system is solved, the message ‘The network was solved successfully’ is displayed in the Results Log dialog.
If the pipe system is not solved, the log offers some suggestions as to why the system could not be solved, and the message ‘The network was not solved. See log details above.’ is displayed in the Results Log dialog. When this happens, review the log and click OK to return to the Drawing pane in design mode. Make the necessary changes to the system to resolve the design errors in the system, and click the Calculate button on the tool bar to recalculate the revised system.
If the Results Log has been closed, it can be re-opened by clicking the Show Log button on the toolbar.
To change back to Design Mode, close the Results Log and then click on the Re-Design button on the toolbar.

Click the View Results Drawing button on the results log to display the drawing with results.
