Researchers have developed a novel hybrid approach for coupling reduced order models (ROMs) with each other and with high-fidelity full order models (FOMs). This method utilizes the overlapping Schwarz alternating method (O-SAM) to address challenges in multiscale modeling, such as long runtimes and complex mesh generation. The technique allows for the integration of disparate models, meshes, and time integration schemes, leading to enhanced computational efficiency and accuracy. Numerical experiments on 3D solid dynamics problems demonstrated speedups of up to 106x compared to traditional FOM-FOM couplings, paving the way for more efficient engineering simulation workflows.
