Errors, Warnings and Log Files

• Error File• written to if analysis fails• error messages point to the problem• empty if run successful

• Warning File• contains assumptions made• non-convergence warnings• parameter out of range and curve extrapolation warnings

• Log File• record of general data entries• record of fluid properties• repeat of errors and warnings• tabulated results data• can be customised

Same Example - Transient

• Model a Transient event• in this case, a varying upstream pressure

• Need some additional data• assign pressure vs time curve• model an elastic pipe with wave

speed of 1000 m/s• time step = 0.011s• analysis run for 5s

• Review results

Assign a Performance Curve

• Curve• Surface• Equation• Stored within an expandable database

Run-Time Displays

• Run-time colours can be applied to a visible schematic to indicate varying• Pressure • Flow Rate• Temperature

• Run-time graphs can also be displayed• These are covered later

NUT 6.3 Slide 36 of 41

Transient Results

• Can plot graphs of time history variations

Different ways of viewing time varying results

Transient Results

• Can overlay component and node results• Can overlay results with different units

• can re-stack the axes
