This document discusses engineering modelling and numerical simulation. It outlines the objectives of discussing breakthroughs in engineering research using simulation, key industries that utilize simulation, and examples of simulation applications. Engineering modelling is a multidisciplinary process that uses computer programs to model physical phenomena and predict system performance, complementing physical testing. Modelling is now widely used across various engineering fields and is attracting more university and industry interest due to its capabilities.

Modelling Attraction
• University faculties and researchers everywhere are more interested in
computing and open to the myriad of computing possibilities than ever
before. This is due to the increased awareness of simulation successes,
important changes in industrial attitude, and the demand for qualified
computational scientists in all areas of R&D.
• Virtual experimentation (modelling), with its increased capabilities for
explanation and prediction, is rapidly gaining ground across a wide
spectrum of industrial and academic activities.
• Students are attracted to engineering modelling and research because they
can easily get good jobs afterwards.

Concluding Remarks
• Modelling is today an equal partner with pure theory, observation (statistics),
and pure experiments in the analysis and solution of engineering problems.
• The availability of high performance computing (HPC) – inexpensive enough
to be available on every researcher’s desk – has changed engineering analysis.
• Engineering modelling is the most modern approach used for scientific
research and engineering design.
• Modelling and Simulation in engineering intend to report leading-edge
scientific contributions from mathematics, computer science, various sub-
disciplines of engineering, management, psychology and cross-cultural
communication, all of which focus on the modelling and simulation of human-
centred engineering systems.
