Agenda - Slick Tricks: Tips & Tricks from the UniSim Design Support team

• Focus on usability features introduced in UniSim Design R450, grouped by theme.- (& reminders of old favourites)

- Live Demos for almost all

• Knowledgebase- The home of the tips and tricks!

- Tips and tricks presentations now available

• Thermodynamics- Control over super-critical region

• User Interface- Taskbar icon displays solver status

- Workbook – quickly set up H&MB and equipment tables on PFD

- Dealing with long lists – Find Row / Column

- PFD PFD Table Format Copy/Paste

PFD Shift+K Hot Key – Change Calculation Levels

Automatically note user specification changes

- Unit set changes in Preferences

• Unit Ops- Spreadsheets

Object names

In R450 <empty> cells within a range (formula) make the formula results show<empty>

<INPERR>

- Unit Op improvements Delta T/Delta P

- Column XML Import / Export

- Transitions – error reporting

• Advanced- Calculation Order Analysis Tool

THERMODYNAMICS

Control over super-critical region

• Prior to R450:

- No obvious indication if stream was in the dense phase

- No control over where the super-critical region appeared

- No choice over phase types used for property calculations

Algorithm described in KB 342

What does the reported vapour fraction mean for a stream in the dense phase?

• R450 gives: (for PR and SRK only) on Parameters2 tab of Fluid Package

- Control over where super-critical region is predicted

- Possibility to override phase type (all or by property – Density, Visc,

Them. Cond.)

- Switchable warning messages

USER INTERFACE

7


Taskbar icon displays solver status

• When UniSim Design is solving the Taskbar icon shows differently.

- Steady State or Dynamics

• For increased performance (e.g. over Citrix/RDP) can minimize but

still keep track of status.

8


Workbook

• Quickly add H&MB / Equipment Summaries to Workbook then PFD

9

New Hide Options for R450 too

PFD Table Format Copy/Paste

• Quickly copy/paste formats between PFD tables

- Copies Font, Colour, Options between tables

- PFD can then be copied to the clipboard for reuse

10


Dealing with long lists – Find Row / Column

• Right click option on long lists (5 or more entries)

- Then ‘type to jump to’

• E.g. Workbook, Stream Properties page,

• Display units Compositions

11

Particularly useful

with ‘show

Indices…’

Preferences option


PFD Shift+K Hot Key – Change Calc Levels

• Hot Keys covered in previous UC Days, find list at

Help – Hot Key List – PFD

• e.g. F2 to change object names

• Existing Shift + L Hot Key shows calc levels instead of names

Press 3 times for streams/ops/both

• Use new Shift+K Hot Key to change levels for objects which are

selected

12


Automatically note user spec. changes

• User may make notes on any object (covered in 2014 UC Day)

• Notes manager available on Flowsheet menu (or Ctrl + G)

• R450 adds a way to automatically note spec changes

- Stream, unit op, fluid package

13


Unit set changes in Preferences in R450

• The Variables tab has some new options in R450

- (Default) set is used when UniSim Design is opened

- User will be prompted if case ‘Preferred’ set is different

14

• Set current

set as usual

• Set (Default)

set by right

clicking

• Set Preferred set

• See which sets

are saved with

case

UNIT OPS

15


Spreadsheets

• Covered in previous UC Days:

- Range formula, insert rows/columns, copy/paste formulae, absolute

references ($), write formulae by clicking, Strings in If function

- Add multiple variables (using Navigator)

• New for R450

- Object Names / Descriptions via Copy Special

- <empty> handling

- <INPERR> indication for broken imports

16


Spreadsheets - Copy Special

• Two new options added for R450

- Variables with Descriptions

- Offset Labels – used to get component names

17


<empty> and <INPERR>

• In R450 <empty> cells within a range (formula) make the formula

results show <empty>

- In R440 they would be treated as zero

• Cells where there was an imported value whose object has now

been deleted show as <INPERR>

- Clear by selecting cell and hitting Delete

18

Automatic fixing tool in KB 1329


Unit Op Delta T / Delta P

• Unit Op improvements

19


Column XML Import / Export

• A means to export Profiles/Estimates/Specs from one to column to

another

- E.g. ‘Same’ column in different variants of the same case

20


Transitions – error reporting improved

• Transition tab now highlights Transitions with issues

21

ADVANCED

2


Calculation Order Analysis Tool

• Tools menu

• Shows the calculation order of all/selected objects

- Total Execution time and the number of times each object is called
