Engineers increasingly turn to multiphysics simulation to capture interacting physics—thermal, electromagnetic, fluid, and structural—in a single virtual environment. According to a recent article from Machine Design, this shift means fewer physical prototypes, faster development cycles, and deeper insights into real-world performance.
One striking example comes from a client working on a device to influence solar radiation absorption and re-emission in the atmosphere. Using software from COMSOL Multiphysics, AltaSim simulated solar loading under different atmospheric and geographic conditions to check whether the concept would function at a global scale, all before building a physical prototype.
In healthcare, multiphysics modeling proved vital to design an electromagnetic wrap that selectively heats implanted knee replacements to eliminate post-operative infections while sparing surrounding tissue. AltaSim’s simulations of heat distribution in human anatomy helped developers win regulatory approval from the U.S. Food and Drug Administration (FDA), saving years and reducing risk compared with trial-and-error prototyping.
Another major win: virtual MRI testing for implants. Multiplying interactions, such as magnetic fields, heat, and structural effects, can now be evaluated in simulation early on. That means many implants can be verified for MRI compatibility long before manufacturing, cutting costly redesign cycles.
AltaSim also promotes building “simulation apps,” simplified interfaces built atop complex models. These let engineers or non-specialists run advanced simulation workflows quickly, without deep expertise.
For mechanical engineers and product designers, this trend means simulation is no longer a niche step but a core part of design, testing, and validation. Whether you are designing energy systems, medical devices, or advanced industrial products, multiphysics simulation offers a path to safer, faster, and cost-effective innovation, often skipping physical prototypes altogether.
