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:
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.
3D electromagnetic problems become more complex in multiphysics simulations such as noise-vibration and harshness (NVH).
Could OnScale's Multiphysics simulation have been the key to solving the global supply disturbance amounting to $400 million per hour? Read the article in Digital Engineering.
To understand what kept emergency devices from deploying fully during an offshore well catastrophe, researchers turned to Ansys Mechanical and Ansys Fluent to model fluid–structure interactions.
This webinar describes OnScale’s revolutionary approach that combines state-of-the-art proprietary multiphysics solvers and cutting-edge high-performance computers on the cloud. We also describe OnScale’s unique technology and business approach, which gives users the ability to run the thousands of simulations required to fully optimize the electronics package using a flip-chip, all in a fraction of the usual time and cost.
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.
Tecumseh engineers used Ansys multiphysics capabilities to design a new compressor that consumes less power and produces less noise in under half the time required to design the previous product.
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.
To design products in the real world, engineers need to contend with physics in the areas of electrical, acoustics, heat, fluids and more. COMSOL is an industry-leading simulation platform that captures the richness of the real world with its multi-physics capabilities.
Verathon is expecting their newest devices to be ready within a 2 month time frame, as opposed to the industry standard 18 month cycle.
