1. Switchable ranking for core candidates — re-sort the top 5 by balanced pick, high reliability, or lowest loss, depending on what matters most for your design. 2. More trustworthy core selection — operating points are now self-consistently recomputed from the actual integer turns ratio, with a new hot-spot gap-permeability recheck that filters out candidates that could drift out of spec at high temperature, so results track real-world winding and thermal behavior more closely. 3. Bmax design ceiling is now optional — leave it blank and the engine guards against saturation automatically using the material's Bsat×70% margin, so an overly conservative guess won't rule out viable designs; set your own ceiling anytime when you need an extra constraint, for a more flexible and realistic filtering process.
