Multiphase CFD
MARIN 3D water-air dam break (research)
Water front impact, splash and reflected waves over 0.05–6 s. Fixed source condition; accuracy assessment failed.
Published scope
The inputs, geometry and outputs below follow the registered public case. Published verification applies only to the stated conditions. Service availability requires a live request.
POD + time-conditioned neural network
A released water column strikes an obstacle, producing splash and reflected waves. The case uses public three-dimensional water-air CFD data with 549,151 cells.
Select a time from 0.05 to 6 seconds to inspect water fraction, velocity and pressure. The model fits time evolution at fixed geometry, materials and initial water depth. All 8 independent full-field final-test frames fail the combined accuracy thresholds. 10 of 12 experimental channels pass; H1 and H3 water heights fail. Results are for research visualization.
