Cover Story: Thermal-fluid topology optimization is often limited by the high cost of Navier–Stokes simulations. We proposed a multifidelity pipeline that performs rapid optimization with a Darcy–convection low-fidelity model, while SEMDOT decouples analysis and geometry to deliver smooth, CAD-ready channel boundaries. By varying inlet pressure and P-norm aggregation, diverse candidates are seeded and then screened using high-fidelity Navier–Stokes–convection simulations in COMSOL. In representative cases, the selected designs reduce peak temperature (from ~337 K to ~323 K) and pressure drop (from ~18.7 Pa to ~12.6 Pa) versus conventional straight channels, and achieve a stronger Pareto distribution than a RAMP-based workflow. View this paper
