The Subject area Modelling and Simulation in Engineering and Sciences deals with the mathematic modelling and numeric simulation of complex systems through the development of new algorithms for calculations.

This area is marked by multi-scale approaches, the validation of models and the quantification of uncertainty. This subject area includes various basic disciplines, such as Physics and Geophysics, Applied Mathematics and the Sciences of Life. It is targeted to the development of innovative methodologies for the modelling and simulation of processes in the mechanical, environmental, civil and energetic fields.

Calculation and simulation methods are used, which derive from sciences and engineering, to be applied in all phases of the life-cycle of an engineered product-system.

The modelling and simulation activities belong to the most advanced research activities, referring to natural and artificial systems, supporting, integrating or replacing complex experiments and theoretical surveys. They are useful tools capable to solve the most important and difficult issues which mark our contemporary life, such as, for example, the creation of sustainable cities and infrastructures, the development of new sources of clean energy and the evaluation of the impacts of climate change on the environment and natural resources.

As a consequence, modelling and simulation are interdisciplinary topics, because of the strong connection among the main sectors of mathematics, physics and geophysics, mechanics and material sciences.
