ABSTRACT

Multiphysics problems at the interface between solid mechanics, fluid mechanics, heat transfer, chemical diffusion and electromagnetism are becoming increasingly important in a wide range of disciplines in engineering. For example, fluid flows can induce displacement and vibrations within solids [1], electro-induced growth can result in material gain [2], chemical absorption weakens materials and drives cracks [3], and thermal fields induce fluid flows [4]. The challenging aspect computer simulations for multiphysics problems have in common is that they require efficient resolution of not just a single field of physics, but also the coupling between different sub-problems. This necessitates developing new formulations, discretization techniques and computer implementations to obtain stable simulations and accurate results, with each of these aspects posing additional challenges unique to multi-physics problems, e.g. mismatching domains or discretization, large ranges of relevant time or length scales, or the coupling scheme itself causing instability within the individual physics included.

This mini symposium aims to bring together researchers working on computational modelling methodologies for a wide range of multiphysics problems. We invite contributions related to Multiphysics modelling in the areas of mathematical and (constitutive) modelling formulations, discretization techniques, coupling schemes, and parallel algorithms for solving multiphysics problems. Example applications might include, but are not limited to, electro-mechanics, magneto-mechanics, fluid-structure interaction, conjugate heat transfer, coupled diffusion-elasticity.
