Rather than globally resolving flow fields via mesh-based discretization, MOS decomposes the system into physically meaningful flow primitives, each represented by a reusable modular operator. These operators are trained offline using a parameterized physics-informed neural network (P-PINN) in a single pre-processing step, and later composed through a physics-guided superposition strategy to approximate the full system-level mapping. The core advantage of MOS lies in its modularization strategy. By learning only small-scale flow primitives offline, MOS reduces the training cost to a fixed, minimal investment independent of system-level complexity. In the online stage, MOS dynamically solves for primitive-level interactions for any specific configuration of a system, then reconstructs the global flow field through the superposition of modular outputs. This two-stage online process, comprising both solving and inference, enables scalable and generalizable predictions. As a result, MOS addresses the curse of dimensionality by reducing high-dimensional systems to tractable compositions of modular operators and overcomes multiscale challenges through a scale-adaptive operator assembly that flexibly resolves flow features with minimal overhead. We demonstrate MOS for static and dynamic arrays of up to <span><math><mrow><mn>15</mn><mo>,</mo><mn>000</mn></mrow></math></span> cylinders in a channel cross-flow (corresponding to roughly <span><math><msup><mn>10</mn><mn>5</mn></msup></math></span> input parameters). All of these configurations are solved using a shared single-cylinder cross-flow modular operator, trained offline in 30 hours using a data-free, physics-informed machine learning strategy. In the online stage, MOS achieves end-to-end flow field prediction at 3 to 5 orders of magnitude speedup over conventional numerical solvers, while maintaining high fidelity (<span><math><mrow><msup><mi>R</mi><mn>2</mn></msup><mo>&gt;</mo><mn>0.85</mn></mrow></math></span> for all cases). Moreover, the MOS solution format requires 3 to 5 orders of magnitude lower memory usage than conventional numerical outputs. Once solved, the solution can be queried in real-time to infer flow variables at arbitrary spatial resolutions or scattered points, enabling flexible and efficient visualization across scales. Additional tests indicate that MOS remains robust to polydispersity and translational/rotational motion of the cylinders.</div></div>","PeriodicalId":352,"journal":{"name":"Journal of Computational Physics","volume":"544 ","pages":"Article 114435"},"PeriodicalIF":3.8,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145334204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the success of machine learning-based methods in learning SDEs, existing learning methods are not applicable to SDEs in bounded domains because they cannot accurately capture the particle exit dynamics. We present a hybrid diffusion model that combines a conditional diffusion model with an exit prediction neural network to capture both interior stochastic dynamics and boundary exit phenomena. Specifically, the proposed hybrid diffusion model consists of two major components: a neural network that learns exit probabilities using binary cross-entropy loss with rigorous convergence guarantees, and a conditional diffusion model that generates state transitions for non-exiting particles using closed-form score functions. The two components are integrated through a probabilistic sampling algorithm that determines particle exit at each time step and generates appropriate state transitions.

The so-called THINC/HAM significantly improves the convergence behaviour of interface reconstruction in terms of the maximum iterative residual and percentage of divergent cells, thus enhancing the local volume conservation of volume fraction.

Numerical analysis is also carried out to investigate the appropriate values of some critical parameters in this method. As verified in the benchmark tests, the present scheme shows considerable improvements in numerical accuracy and robustness even if a larger time step and distorted unstructured grid are used.
