gPROMS v3.1 is packed with features that simplify the work of model developers – for example, experts within an organisation's modelling group – and model users – for example process engineers who want to create flowsheets from existing models, or operations personnel who simply want to execute a completely pre-configured model.

In particular, new facilities for result management and presentation make it easy to display results in many different ways.

Features at-a-glance

This page outlines some of the key features. For more information see the release notes or request an on-site update for your company.

Details

Click on the images below to enlarge

Flowsheets can include plots, result fields, images and text

Plots, display fields and other items are draggged from the Annotations palette

Custom reports can include plots that are updated during the run

The layers construct helps to separate information into manageable subsets

 

Entities can be grouped and moved, cut-and-pasted or grouped within other groups

Large flowsheets can be printed in multiple sections

 

 

 

Multi-dimensional plots are now possible

 

Drag-and-drop addition of results to flowsheets

A major enhancement of v3.1 is that flowsheets can now include displays of key variables in the form of value tables and plots.

The workflow for creating these additions is very straightforward. Items are placed on the flowsheet by dragging-and-dropping them from the palette, followed by a configuration step – for example, specifying the image or the variables to be displayed.

Results are udated as execution progresses. Alternatively, you can view results post-execution by (for example) stepping through the simulation timeline.

Drag-and-drop addition of images and text

Flowsheets can be further enhanced by adding free text or images – for example, company logos or pictures of units or plants.

As with results items, images and text are accessed via the palette.

Enhanced model reports

Model developers can now create custom reports for any model, for the quick display of key results.

Results can be displayed as value tables, 2-D or 3-D graphs as well as XY plots.

Reports are associated with each instance of a model (including the top-level flowsheet) and can be accessed through the trajectory tree of a result Case.

All models in PSE’s Process Model Library (PML) are now provided with a customisable report template.

Layers

the layers construct – a new concept in gPROMS – allows you to select which items on a flowsheet are visible and which are printed.

See the screenshots on the right (click to expand). The top left screenshot shows only the process flowsheet. From clockwise, the following are added: control schemes, results and a description of the process.

Specification and selection of layers is done via a simple dialogue accessed from the topology toolbar (right lower).

Automatic and manual layout of connections

The automatic line routing in gPROMS has been significantly improved.

In addition, users now have complete control over routing of flowsheet connections and the line style of a connection (previously these were handled automatically).

It is possible to route each line on the flowsheet manually, by repositioning each segment of an individual connection or by adding or removing segments.

This results in cleaner and easier-to-understand flowsheets.

Grouping

Any items on the flowsheet – units, text boxes, graphs, value tables – can be grouped together, in order to simplify construction and maintenance of flowsheets.

Groups can be moved or resized as a whole, and can be combined into nested groups.

Printing facilities

New print facilities now allow much easier printing of large graphical flowsheets.

The printing facilities now allow printing of topologies, model reports or the summary results of optimisations, parameter estimations and optimal design of experiments.

Flowsheets can be printed on any paper size supported by your printer. If the maximum available size is not sufficient, the printout can be distributed over multiple pages, with crop marks for assembling the complete layout.

An important new feature is the introduction of a preview which allows finer control over contents and layout.

Support of scalable vector graphics (SVG)

Scalable Vector Graphics (SVG) images can now be used as model icons or as inline images in flowsheets or model reports.

It is now possible to link graphic attributes such as size and colour to process variables – for example, to change the colour of an icon depending on temperature, or to add a level display to a tank.

SVG images greatly enhance display quality when viewing flowsheets at a higher magnification and when printing.

Results management: enhancements to plotting of multi-dimensional data

Result trajectories stored in a Case already allow displaying variables in tables or plotted as 2-D and 3-D graphs.

For multidimensional variables it is also possible to plot one dimension as a series. In the example on the right, the trays have been displayed as a series.
