The philosopy behind gPROMS v3

"A modelling platform to 2020"

The philosophy behind the new-generation gPROMS is described by PSE Managing Director Costas Pantelides:

Companies … need to know that their investment is secure

v3.1: ten times faster and just as accurate

The results of using an exponential transformation to generate a non-uniform grid: virtually identical results with 10 times fewer discretisation points and a solution ten times as fast as the original.

v3.2: and still faster"

In one case the number of variables was reduced by a factor of 40% and simulation time by a factor of 35%.

PSE is committed to advancing the gPROMS numerical solution engine as well as the usability features

"The leading process industry companies are becoming serious about capturing their IP in mathematical models and systematically using these to accelerate innovation and manage risk.

As companies move their IP from legacy code and traditional flowsheeting environments they need to know that their investment is secure. We have ensured this with a seamless transition to a completely new generation of gPROMS software that will remain state-of-the-art for a decade or more.

As with any other product, software grows old. It may not 'wear out', but it becomes obsolete: new languages, conventions, techniques and facilities become available; concepts and methodologies become refined and advanced through continual R&D. Only by a process of continual renewal can you bring these advances to users effectively, and this is the motivation behind the completely re-architected gPROMS v3.

Our intention with v3 is to combine the best of all worlds – powerful custom modelling within an easy-to-use graphical flowsheeting environment of the type instantly familiar to process engineers. This means that the whole range of modelling and optimisation functions important to process organisations is available within one environment."

Third-generation advanced process modelling

The gPROMS 3 development, while the second generation of the gPROMS product, is third-generation advanced process modelling, in a process that began with the original SPEEDUP project at Imperial College in the 1980s (generation 1).

This continued with the development of the first gPROMS platform (generation 2), which took a 'clean sheet' approach to the original concepts while adding essentials such as a task language for handling of batch process systems, distributed systems modelling and full parameter estimation and dynamic optimisation capabilities.

gPROMS v3 (generation 3) represents a complete rewrite of the underlying technology, coupled with a state-of-the-art user interface, to provide the most modern – and most powerful by a long way – modelling platform available to the process industries.
