What is multiphysics simulation Software?
Multiphysics simulation software is used to model and analyse complex interacting physical processes. This analysis enables engineers, scientists, and researchers to study how physics interact and influence each other in a component or a system. Multiphysics simulation software offers engineers a comprehensive and realistic representation of real-world operations and provides insights into how products that are subject to interacting physical forces might perform. Here are some of the challenges multiphysics simulation can solve:

• Interdisciplinary simulation: Multiphysics simulation combines multiple physics disciplines, such as fluid dynamics, structural mechanics, heat transfer, and more. Crossing these discipline boundaries can be challenging for businesses. This is why Hexagon invests in creating interoperable solutions designed to work together.
• Complex interactions: In real-world systems, physics are not isolated. They interact and affect one another. Multiphysics simulations model these interactions to help engineers understand how iterative design changes will impact performance across multiple physics disciplines.
• Optimization and design: Engineers use multiphysics simulations to optimise the design of systems and devices. They can iterate quickly and confidently and use the results of their analysis to enhance performance, efficiency, and reliability while minimizing costs.
• Predictive analysis: Multiphysics simulations offer insights into how a system or device will behave under different conditions. This is especially valuable in industries like aerospace, where these conditions are too costly to test through physical prototypes alone and understanding how an aircraft structure reacts to external forces, thermal loads, and aerodynamics is crucial for safety and durability.
• Prototyping reduction: By performing virtual tests and analyses with multiphysics simulations, companies can reduce the need for physical prototypes and save time and resources.
• Safety and reliability: Multiphysics simulations can assess the safety and reliability of systems. For instance, in the nuclear industry, these simulations help predict how materials behave under conditions that are too extreme for safe physical testing.
• Innovation: Multiphysics simulations help engineers push the boundaries of knowledge and innovate by exploring the development of new technologies and materials.
• Product performance enhancement: Multiphysics simulations can help engineers identify weaknesses and opportunities for optimization early in the design process, allowing them to optimise products and ensure manufacturability.

What is multiphysics coupling?
When one physics solution affects the other, they are ‘coupled’. Depending on how strongly coupled the physics are, different mathematical methods may be used to improve the accuracy of the analysis. As an example, consider the physics of aircraft wings. For aero-acoustic calculations, the fluid flow strongly affects the acoustics, but the acoustics do not affect the fluid flow (in most cases). The physics can be coupled by solving them in sequence, using the best methods for each and maximising accuracy and speed. For an aircraft wing, however, the fluid flow affects the structure and the wing deformation affects the fluid flow, so both simulations should run in parallel while exchanging information with each other as they search for a converged state for each physical time step.

What is Hexagon’s multiphysics suite?

Is multiphysics software necessary for building digital twins?
Multiphysics capabilities are highly recommended for building accurate digital representations of reality. The more complex a product becomes, the more likely it is that multiple physics will be needed to fully capture it as a digital twin.
