I need a COMSOL Multiphysics model of a high-frequency transformer that couples the electromagnetic and thermal physics so I can focus on thermal stress impacts. The goal is to see exactly where mechanical strain develops inside the core, windings, and insulation as temperatures rise during high-frequency operation. You’ll start from the transformer’s geometric and material data (I’ll supply those) and build a 3-D electro-thermal study that includes frequency-dependent copper and core losses, convection or forced-air boundaries, and, ideally, a transient run that tracks hot-spot evolution. Once the temperature field is solved, the model should translate that field into the corresponding thermal-induced stresses so I can compare stress levels against material limits. Bec...

I have a set of simple, round printable parts that came from an AI-generated file. Before I can put them on the printer I need you to tidy them up: every surface should be smoothed, all stray vertices removed and, most importantly, the shells must be closed so the slice engine recognises a single, watertight volume. Those parts also have to work together mechanically. Please propose and implement a practical way for them to open and close—threads, snap-fits, magnets, screws, anything is acceptable because using tools is fine. Explain the approach first so I can sign it off, then integrate it. Finally, I want to scale the assembly so the “eye” opening lines up with a 1.3-inch OLED (30 mm × 15 mm). The internal cavity of the main body must stay above 80 mm in height...
