🧪 Flash Calculation Predictor
Upload feed data to predict the equilibrium phase split (x, y, L) with a neural-network ensemble and get physics-consistency metrics. Include ground-truth compositions to also score accuracy (R²). All computation runs privately in your browser — your data never leaves your computer.
Predictions are the mean of the scheme's 7 cross-validation folds;
the per-fold spread is reported as uncertainty.
the per-fold spread is reported as uncertainty.
Sets the Peng-Robinson constants used for the iso-fugacity residual.

The neural models were trained on a C1/C3/C14 system over a fixed pressure range at 353 K; predictions on inputs far outside that domain will degrade — watch the physics residuals and the ensemble uncertainty. Files above 100,000 rows are truncated to keep in-browser compute responsive; large inputs may take up to a minute or two to run.
