⚡ The Strategic Hook: $O(n^3) \rightarrow O(1)$

Traditional CAE solvers (FEA/CFD) scale at $O(n^3)$ complexity, creating a massive computational bottleneck as mesh density increases. This framework demonstrates the shift to Physics-Informed Neural Networks (PINNs) and Neural Operators, reducing time-to-solution to $O(1)$ inference.
