Flexi-VAE: Unified PDE Prediction Interface

🚀 Flexi-Propagator: Single-Shot Prediction for Nonlinear PDEs

Governing Equation (1D Burgers' Equation): $$ \frac{\partial u}{\partial t} + u \frac{\partial u}{\partial x} = \nu \frac{\partial^2 u}{\partial x^2} $$ Key Advantages:
✔️ 50-100× faster than AE-LSTM baselines
✔️ Parametric control: Embeds system parameters in latent space

Physically Interpretable Latent Space - Disentanglement:

$$ Z_1 \text{ Encodes Peak Location, } Z_2 \text{ Predominantly Encodes Re (Sharpness)} $$
