Objective
Demonstrate that Fugu, WINTS’ numerical engine, can reproduce the benchmark experiment described by Kleefsman et al. while keeping runtime low.
Simulation setup
The case uses a 402,500-cell mesh to capture interactions between water, air, and the solid obstacle. WINTS pre-launch checks validate the setup and recommend the optimal processor count.
- 3D domain with 402,500-cell mesh and adaptive timestep
- Automatic resource recommendations and input-compliance checks via WINTS guardrails
- CPU count: 20
- Native multiphase handling, avoiding complex remeshing
Results & validation
Water height (H1–H4) and pressure (P1–P2) probes match published measurements. The full run completes in about two hours, demonstrating the efficiency of a well-tuned HPC configuration with Fugu.
