Design Principles

"Computational modelling (e.g., FEM) is essential for validating complex engineering designs before physical realization, particularly for systems with stringent performance and safety requirements."

This research demonstrates how computational modelling can de-risk the development of complex systems like dual-temperature refrigerated containers. By simulating stress behaviour and thermal performance, designers can optimize designs before physical prototyping, saving time and resources.

What This Means for Your Design

Using computer simulations (like FEM) helps designers check if their ideas for special refrigerated boxes will be strong enough and keep the right temperatures for both cold and frozen food, before they even build one.
