Metamodelling provides a way of modelling the rules underpinning not only modelling languages such as UML but also processes. In the context of object-oriented development, we evaluate the conceptual framework used to reason about metamodelling from the different perspectives of methodologist, method engineer and software developer. We propose the use of clabjets and powertype patterns as a sol...

Atomistic simulation can provide kinetic and dynamical insight into the fundamental component processes underlying both mass-transport and plasticity within a solid. To directly extrapolate atomistic simulation results to the experimental time-scale is however difficult and remains a general challenge to the atomistic modelling community. This is particularly the case when performing simulation...

Recently, we have witnessed a growing need to involve business people in the early stages of Enterprise Information Systems development. The MAP methodology appears to be a good candidate for involving business people in the early modelling of business applications, reducing the risk of business-IT systems misalignment. Furthermore, in the context of Model Driven Engineering, such a methodology...

Solid Freeform Fabrication (SFF) processes have demonstrated the ability to produce parts with locally controlled composition. In the limit, processes such as 3D Printing can create parts with composition control on a length scale of 100 m. To exploit this potential, new methods to model, exchange, and process parts with local composition control need to be developed. An approach to modeling a ...

The rising popularity of incineration of municipal solid waste (MSW) calls for detailed mathematical modelling and understanding of the incineration process. In this paper, governing equations for mass, momentum and heat transfer for both solid and gaseous phases in a moving bed in a solid-waste incineration furnace are described and relevant sub-models are presented. The burning rates of volat...

We investigate the influences of modelling assumptions on the dynamic behaviour of collapsible channel flows. The elastic wall is modelled in various different ways: as a large strain Bernoulli–Euler beam, as a small strain Timoshenko beam, and as a 2D-solid model derived from a general virtual work approach, using small strain or large strain assumptions. Different inlet boundary conditions ar...

This paper analyses the numerical stability of coupling procedures in modelling the thermal diiusion in a solid and uid with continuity of temperature and heat ux at the interface. A simple one-dimensional model is employed with uniform material properties and grid density in each domain. A number of diierent explicit and implicit algorithms are considered for both the interior equations and th...

The paper studies the interaction of a periodic solid bristle structure with a fluid. Such problems arise, for example, when modelling biotechnological devices operating in liquids or when simulating epithelium surfaces of blood vessels. The fluid is described by the linearized Navier– Stokes equation whereas the solid part is governed by equations of linear elasticity. The interface conditions...
