15
NUT 6.3 Slide 15 of 41 Text Options Text can be associated to the nearest component or super-component The options can be accessed by ‘alternate’ clicking on the network schematic
16
NUT 6.3 Slide 16 of 41 Configuration Files Network configuration settings can be defined Allowing changes to colours, text and options These can be stored as group or individual preferences
17
NUT 6.3 Slide 17 of 41 Component Data Entry Allows selection of different friction options ( NB. Steady State filter set) Collection of components to update Subform expanded Information about the specific data item
18
NUT 6.3 Slide 18 of 41 Copy Data Any data item that has a tick is copied Copy Method :
19
NUT 6.3 Slide 19 of 41 Component Data Required Upstream pressure source total pressure = 1.5 bar Discrete loss area = 7.85x10 -3 m 2 forward loss coefficient = 50 reverse loss coefficient = 50 Pipe length = 100 m friction option 1 roughness = 0.025 mm diameter = 0.1 m Orifice pipe diameter = 0.1 m orifice diameter = 0.05 m Downstream pressure source total pressure = 1 bar
20
NUT 6.3 Slide 20 of 41 Component Collection Criteria
21
NUT 6.3 Slide 21 of 41 Node Data Entry Specify collection of nodes Add specfic node number to list Table of nodal data
22
NUT 6.3 Slide 22 of 41 Node Collection Criteria
23
NUT 6.3 Slide 23 of 41 Node Data Required Elevations shown All nodes are ‘wet’ No nodes have the autovap model
24
NUT 6.3 Slide 24 of 41 General Data Same sheet as for component data entry Data required: fluid type Water (SS) Hydrol 46 (FS) ambient temperature = 20 o C atmospheric pressure = 1 bar Start
25
NUT 6.3 Slide 25 of 41 Analyse Proceed with analysis? Analysis progress Analysis completed Success? View Errors if No View warnings if Yes
26
NUT 6.3 Slide 26 of 41 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
27
NUT 6.3 Slide 27 of 41 Results List of results available Gives details to help identify particular results sets Open, description and delete options become available when the result is selected
28
NUT 6.3 Slide 28 of 41 Component Results Can draw results on network including colour coding Create gradient of results Can obtain list of results Steady State results
29
NUT 6.3 Slide 29 of 41 Node Results Can collect nodes to display results Plot graph of results Can see results on network diagram Table of node results
30
NUT 6.3 Slide 30 of 41 Node Result Pressures at node level displayed on network diagram
31
NUT 6.3 Slide 31 of 41 Node Result Plotting area Three buttons that allow single line on graph overlay facility keep graph when another is plotted
32
NUT 6.3 Slide 32 of 41 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
33
NUT 6.3 Slide 33 of 41 Assign a Performance Curve Curve Surface Equation Stored within an expandable database Will cover the database features later
34
NUT 6.3 Slide 34 of 41 Curve Selection
35
NUT 6.3 Slide 35 of 41 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
36
NUT 6.3 Slide 36 of 41 Transient Results Can plot graphs of time history variations Different ways of viewing time varying results View results from a branch of a component Different ways of viewing the results independent of time Select an internal node within the pipe With Time selected results can be animated after analysis List of components in the network
37
NUT 6.3 Slide 37 of 41 Transient Results Can overlay component and node results Can overlay results with different units can re-stack the axes
38
NUT 6.3 Slide 38 of 41 View of Log File Data contained can be customised Useful if wish to extract certain results e.g. for inclusion in a report Define in ‘Report’ when results selected Can also view warnings and errors files
39
NUT 6.3 Slide 39 of 41 Creating a Customised Log File Select here to view entire log file Select here to view customised log file Select to view errors or warnings files To view the log file as defined below Can add new customised log file, edit an existing one or delete one. This area is specific to AC analyses and provides different options for displaying P-h diagrams.
40
NUT 6.3 Slide 40 of 41 Customising a Log File Can define data to include: component node specific parameters
41
