Lid-driven cavity PINNs

PINN velocity accuracy across Reynolds numbers.

Status: Ongoing research. Results below are from the specified reduced-budget experiment, not the upstream full-budget configuration.

Experimental setup

Reduced Apple MPS study at Re = 10, 100, 400; three seeds per Reynolds number and verified finite-difference reference.

Next steps

Run nine full-budget CUDA experiments and compare with the reduced-study results.

For reproducibility, consult the repository's configuration files, scripts, saved results and scientific audit.
