| 1. | Lewis R.W.♦, Postek E., Gethin D.T.♦, Yang X.S.♦, Pao W.K.S.♦, Chao L.♦, Numerical methods in simulation of industrial processes, AET2006, First International Conference on Advances in Engineering and Technology, 2006-07-16/07-19, Entebbe (UG), pp.764-795, 2006 Streszczenie: The paper deals with an overview of some industrial applications leading to a formulation for advanced numerical techniques. The applications comprise squeeze casting processes, forming of tablets and petroleum reservoir modelling. All of the problems lead to solutions of highly nonlinear, coupled sets of multiphysics equations. Słowa kluczowe: squeeze forming, powder compaction, oil fields, coupled problems, thermomechanics, porous media, fluid flow, nonlinear solid mechanics, phase transformations, microstructural solidification models, numerical methods, contact problems, discrete elements, finite elements.

| 1. | Ahmad R.♦, Gethin D.T.♦, Lewis R.W.♦, Postek E., Design sensitivity of a sequentially coupled problem: casting, ACME 2004, 12th Association of Computational Mechanics in Engineering Annnual Conference, 2004-04-05/04-06, Cardiff (GB), pp.1-4, 2004 Streszczenie: The presented paper deals with the design sensitivity of a sequentially coupled thermo-mechanical problem. The key finding is to provide a tool for optimisation software (analytical design sensitivity gradients) for a sequentially coupled thermal-mechanical problem.

| 2. | Postek E.W., Lewis R.W.♦, Gethin D.T.♦, Ransing R.S.♦, Finite element model of mould filling during squeeze forming processes, ACME 2004, 12th Association of Computational Mechanics in Engineering Annnual Conference, 2004-04-05/04-06, Cardiff (GB), pp.1-4, 2004 Streszczenie: During mould filling due to decreasing of liquidus temperature takes place solidification pocess. The paper deals mostly with a presentation of an application of a microstructural solidification model. The Navier Stokes equation describing the flow problem is solved using Taylor Galerkin method.
