COMSOL Electro-Thermal Transformer Model
Budget: $30 – $250 USD
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.
Because I need the results ASAP, I’m looking for someone already comfortable with the Electromagnetic Fields (mf), Heat Transfer (ht), and Solid Mechanics (solid) interfaces in COMSOL, and who can automate post-processing for temperature, von Mises stress, and safety factor plots.
Deliverables:
• COMSOL .mph file with all study steps and parametric sweeps
• Short PDF summary (methodology, key plots, and interpretation)
• Quick-read setup guide so I can rerun or tweak the study myself
Hand-off of the first working version within a week would be ideal, with a brief revision window right after. If you have previous transformer or inductor thermal work in COMSOL, feel free to mention it when you reply.
