Researchers have developed a novel method for training neural surrogates for thermo-fluid field predictions, utilizing a label-free approach based on minimizing finite-volume method (FVM) residuals. This technique, applied to attention graph neural networks, bypasses the need for costly labeled training data typically generated by conventional numerical solvers. The FVM-loss model demonstrated strong performance, achieving low error rates on steady-state benchmarks and outperforming data-supervised methods on transient cases while eliminating data-generation expenses.
