RealPDEBench: fluid–structure interaction

Goal

Forecast coupled wake and structural-response dynamics under real/simulated data mismatch.

Recommended models

PIBERT, FourierFlow, FNO, DeepONet, UPT, Transolver, and a DMD baseline.

Critical checks

• preserve the numerical/real split;
• report error separately for fluid and structural quantities;
• evaluate phase and dominant-frequency accuracy;
• include uncertainty or risk coverage for OOD forcing.
