PIML-OFEM: A New Large-Scale Structural Analysis Method Based on Problem-Independent Machine Learning and Overlapping Finite Element Technique
PIML-OFEM couples oversampled numerical basis functions, partition-of-unity overlapping finite elements, and a U-Net surrogate to analyze large heterogeneous structures using only corner-node degrees of freedom.
