Abstract
Abstract The CFD-based geometric optimization of lateral inlet/outlets in pumped storage power stations (PSPS) is bottlenecked by repetitive global remeshing during iterative design, rooted in the lack of persistent correspondence between continuous geometric models and discrete meshes; existing persistent-naming mechanisms address intra-CAD exchange but do not bridge this representational boundary. This study develops an automated CAD/CAE integration framework through three coupled contributions. First, Universally Unique Identifier (UUID) is repurposed as a cross-representation mediation that binds Boundary-Representation entities to mesh regions through a bidirectional mapping, with persistence under topological mutation enforced by a parent–child genealogy rule. Second, change detection, breadth-first influence propagation, and a geometric-deviation termination are coupled into a bounded-update chain operating at the entity level rather than the cell level. Third, conventional wireframe-to-surface reconstruction is extended to topologically variable geometries through UUID-tracked edge genealogy. Validated on three cases, the framework maintains reconstruction accuracy below 0.01 mm; simulated velocity profiles agree closely with physical model tests (RMSE < 0.06 m/s), and it reduces cumulative pre-processing time by 80.6% ± 0.8% relative to commercial parametric solutions over nine design iterations per case, with a 100% convergence rate.
