The core interest of the Process Systems Engineering group, associated with the Chemical Engineering Department of NTNU, are models based on the argument that they are omnipresent in model-based engineering. Both research and teaching builds around models:

EC Framework 7 Project MoDeNa (3 years project completed 2017)   :

MoDeNa aims at developing, demonstrating and assessing an easy-to-use multi-scale software-modelling framework application under an open-source licensing scheme that delivers models with feasible computational loads for process and product design of complex materials. The use of the software will lead to novel research and development avenues that fundamentally improve the properties of these nanomaterials. As an application case we consider polyurethane foams (PU), which is an excellent example of a large turnover product produced in a variety of qualities and of which the properties are the result of designing and controlling the material structure on all levels of scale, from the molecule to the final product. Polyurethanes are used in furniture, automotive, coatings, construction, thermal insulation and footwear, which are the most important industry sectors. Tailoring these properties requires understanding and detailed modelling of the fundamental material behaviour on all scales. An open-source software-suite will be constructed that logically interlinks scale and problem specific software of our university groups, using a software orchestrator that communicates information utilizing our proposed new communication standard in both directions, namely upwards to the higher scale and downwards to the lower scale. This feature is unique, enabling the solution of complex material design problems. By that this project contributes to strengthening the European leadership in design and production of nanocomposite materials with functional properties in general. It will also contribute to strengthening European SME positions in the development of computationally intensive simulation software. Finally, it will contribute to making production processes more efficient by combining scale-specific software tools thereby decreasing the time-to-market. This will enable the exploration of many more alternatives eventually leading to improved products and processes.

EC Horizon 2020 project MarketPlace (started 2018 for 5 years) – link to come

The MarketPlace consortium will utilise state of the art information technologies to build an open web-based integrated Materials Modelling and Collaboration platform that acts as one-stop-shop and open Marketplace for providing all determining components that need to be interwoven for successful and accelerated deployment of materials modelling in industry. This includs linking various activities and databases on models, information on simulation tools, communities, expertise exchange, course and training materials, lectures, seminars and tutorials. The proposed MarketPlace will be a central-hub for all materials modelling related activities in Europe and provide tangible tools to connect disparate modelling, translators, and manufacturing communities to provide a vibrant collaboration web-based tool for the advancement of materials modelling in European manufacturing industry. The developed platform will include mechanisms for the integration of interoperable set of advanced materials model workflows for coupling and linking of various discrete (electronic, atomistic,
mesoscopic) and continuum models. This will be achieved by developing open and standard post and pre-processing methods that allow complex flow of information from one model to another for both strongly and loosely coupled systems. The Marketplace platform will include access to concerted set of federated databases of materials models, materials data and provide for access to experimental characterisation and stimulate the development of interface wrappers and open simulation platforms. The MarketPlace consortium aims to strengthen the competitiveness and lower the innovation barrier for European industry for product development and process design and optimization using materials modelling.

Computer-based modelling

Main activity is in the construction of computer-aided modelling tools that enable a process of systematically constructing, manipulating, expanding and simplifying process models. The realisation is a hierarchical ontology-based software suite that supports

  • graphical construction and editing of process models
  • library of process component models
  • generation of documentation and code for different target environments, both for commercial public programs

Time-scale-based analysis

Multi-wavelets are the base of this area that encompasses process identification, observer design and data concentration.

Hybrid :: mixed discrete / continuous systems

Main subjects that were covered over time include:

  • discrete-event dynamic models of continuous plants observed by a quantising measurement unit and a event-driven input
  • fault detection and identification
  • hazop analysis

As a side product event-driven control of interactive software evolved over time, which is largely being used in the design of the software tools in computer-aided modelling.
