Simulation Software

LSM Solidworks

Solidworks is the standard for drawing things in three dimensions, making it ideal for checking form and fit. Not only does it do away with the drafting table and rule, but its output can, in turn, become input for a 3D printer to actually turn the virtual model into a quick-turn physical prototype. In addition, Solidworks output can be fed to finite element analysis (FEA) software to check the mechanical properties of a design. Give an FEA program a Solidworks design, add information on the materials being used, and it will tell you how well that object will withstand a variety of stresses—how it will handle being dropped or respond to heat.

Of course in the design of transformers and other magnetic devices, electrical properties are at least as important as mechanical ones. That’s where Maxwell 3D comes in. This program models real-world performance in complex magnetic situations, allowing operators to model flux density, field strength and other performance aspects of a design. The simulation can take time, but for complicated designs it’s far faster than developing tooling and actually building samples to see how they perform under load. And because Maxwell 3D can take a lot of time, Precision often uses its proprietary CBX software, which doesn’t require a Solidworks drawing and can quickly do the calculations and tell whether a design is workable.

Best of all, Precision’s simulation software is compatible with the software a lot of our customers use.

Our Solidworks designs can plug right into a customer’s Solidworks design to see, for example, how our transformer will fit into the customer’s device. And our Maxwell 3D results can be input to a customer’s Simplorer software to simulate the performance of a complete electronic system.
