How Not to Miss the Boat with Multiphysics Simulation

Multiphysics Modeling, Simulation / By

Multiphysics simulation is a complex, powerful computational technique that lets you explore all the real-world physical interactions that a complex product may encounter during use including fluid dynamics, electromagnetism, acoustics, and optics. When you’re designing and testing a product with a low to no error margin, Multiphysics simulation is extremely accurate. Take for example the …
