“Multiphysics simulation enabled us to check the feasibility of a technical concept quickly, then optimize the quality, robustness, and cost of a product during the development,” said Matthias Richwin, senior manager for technology development and qualification using simulation at KOSTAL. Understanding this mechatronic component allowed KOSTAL to meet both industry and consumer demands.
Miele effectively optimizes products with simulation and CAD integration
As large-scale design optimizations are carried out across design teams, another essential requirement of successful multiphysics software is revealed: integration with CAD software. As comprehensive improvements are made to a model, these changes must be reflected in real time in the CAD model, enabling updated models to be easily shared for continued analysis and optimization. This capability proved to be invaluable at Miele & Cie. KG, where engineers used CAD parameterization and simulation to optimize an induction stove-pot system design.
Researchers at mieletec FH Bielefeld, a joint research laboratory between Miele and the University of Applied Sciences Bielefeld, Germany, received CAD geometries from Miele containing induction stove designs. As mieletec researchers modified and optimized the design, they were faced with numerous design challenges that necessitated continuous updates and revisions to the original CAD files.
“One of the biggest issues we faced was reducing the high-pitched noise that the pots emit when eddy currents are passing through them,” said Christian Schröder, co-founder and scientific director of mieletec. “The only way to eliminate the noise is to adjust the frequency of the alternating current and coil geometry, so that the noise produced is at a higher pitch than what the human ear can pick up.”
As these optimizations were made, the simulation and CAD models were successfully integrated as improvements were made the final design and the updates were shared with other design teams working on the project. “Using simulation, we found the recipe for current frequency and coil design that produced the least amount of noise possible,” concludes Schröder, and these final designs were used to develop Miele’s award-winning induction stoves.
When simulation is mission-critical, multiphysics is the answer
The multiphysics approach encompasses the use of multiphysics simulation software throughout all phases and aspects of the design process, from the conceptual phase of product development, until a product is delivered to the market -- and after as new discoveries lead to continuous design improvements. Multiphysics software must offer all the tools needed to create a successful product, including geometry, physics, meshing, solvers, and post processing tools, in addition to a unifying environment where multiple physics can be simulated and analyzed.
The ability of multiphysics simulation software to provide accurate and reliable information about a product is positively influencing the product development process. With multiphysics, engineers are finding that there is a tremendous reduction in the resources needed to bring an innovation to market, therefore saving both time and money, in addition to delivering a safer and more reliable product.
