What Is Multiphysics Simulation?

Need to analyze interacting physical fields? Then you need Multiphysics Simulation!

For many engineering analyses it’s sufficient to focus on a single type of physics such as structural mechanics, heat transfer, fluid dynamics, acoustics, or electromagnetics.  However, there are many problems where multiple physics fields are important and interact, which means they must be considered together to achieve accurate enough engineering predictions.

The use of engineering simulation to analyze such problems requires Multiphysics simulation, in which multiple physical fields concurrently drive the behavior of a design and are coupled according to different interaction mechanisms. Some common examples of Multiphysics include:

  • Fluid-structure interaction, such as aeroelasticity, when an elastic structure is deformed by fluid flow
  • Electromechanical interaction, such in piezoelectric materials operating at RF frequencies
  • Structural-acoustics interaction, where vibrating structures interact with acoustic waves in an adjacent fluid medium

With the ever-increasing compute power available for engineering simulation, the range of Multiphysics applications that can be successfully simulated continues to grow. Perhaps the next great advances in this area will be (1) solvers with sufficient computational scalability to achieve realistic multiphysics simulation of highly complex industrial products and devices, and (2) workflows that make powerful multiphysics simulation more accessible and robust for a broader range of engineers.

Multiphysics Simulation of an EV Inverter

As engineers strive for the optimal design solution, a multiphysics approach is essential to fully capture the real-world interactions between different physical phenomena. Physical prototyping can amount to a huge investment in time and cost, meaning running analyses across multiple physics earlier in the design process is key.

Why are simulation jobs exploding in complexity and size, and perhaps more importantly, what can you do about it?

In a recent panel discussion in the DE Hot Seat webcast series, Gabriel F. Dambaugh, owner and principle engineer of FEA Services; and Donald Tolle, Director of Simulation-Driven Systems Development Practice, CIMdata, discuss the rise of multiphysics simulation driving the use of simulation, the software developers' efforts to make their solvers run faster, and the pros and cons of the emerging cloud-hosted solutions.

CFD & Multiphysics Simulation

CFD simulates the flow of liquids and gases by performing millions of numerical calculations. CFD analysis is typically carried out earlier in the design process even before the first prototype is made. With high-speed supercomputers, better designs can be achieved quicker, faster, and cheaper. Multiphysics is advanced CFD involving multiple physics coupled to mimic the real behavior as accurately as possible.

Multiphysics

Multiphysics simulation lets you explore real-world physical interactions a complex product may encounter. These interactions can impact product performance, safety and longevity. Fluid forces, thermal effects, structural integrity and electromagnetic radiation can affect performance. If you isolate these forces and examine them separately, you may not get an accurate prediction of product behavior.
