arXiv:2605.27968v1 Announce Type: cross Abstract: Deploying Scientific Machine Learning surrogates in industrial CFD workflows requires adapting pretrained models to new vehicle families without large datasets; yet whether geometric representations learned by a geometry encoder transfer to topologically distinct shapes remains unvalidated. We address this through leave-one-family-out experiments on a 61.47M-parameter Transformer surrogate (AB-UPT) pretrained on four vehicle families (411 external aerodynamics cases) and adapted to the held-out fifth with only 20 samples. Three strategies are c
The proliferation of complex industrial design processes demands more efficient and scalable computational methods, making the adaptation of AI surrogates to new scenarios a pressing challenge.
This work demonstrates a key advancement in deploying Scientific Machine Learning (SciML) for industrial applications, potentially drastically reducing the cost and time of complex engineering design cycles.
The ability to effectively transfer knowledge from pretrained AI models to new, topologically distinct vehicle families with minimal new data significantly broadens the applicability and efficiency of AI in engineering design.
