The GTOC Universal Engineering Solver is a computational tool designed to bridge the foundational physics of the General Theory of Correspondence (GTOC) with applied macroscopic engineering. By utilizing the framework's established volumetric state-space floor of 10^{-31} meters scaled to the 10^{122} cosmological boundary, this solver allows researchers to calculate the absolute structural energy debt and peak power limits of any physical displacement event. Rather than relying on localized chemical or kinetic potentials, the tool calculates the precise geometric vacuum tension required to maintain or re-tessellate a given macroscopic volume. ⠀ Mechanics & Applications: The Python-based solver requires only two standard empirical inputs: the Displacement Volume ($V_{void}$) of the physical anomaly and the State Change Duration ($\tau$). It applies the fine-structure constant ($\alpha$) as the geometric-to-electromagnetic coupling bridge to output the exact number of displaced lattice nodes, the resulting energy yield in Joules, and the structural peak power limit in Watts. Version 1.1 includes pre-configured testing modules demonstrating the framework's scale-invariant accuracy across seven extreme domains: fluid dynamics (cavitation), high-density energy storage, aerospace structural fatigue, zero-latency silicon architecture, quantum qubit decoherence, astrophysics (stellar core collapse), and geophysics (tectonic slip). ⠀ Usage: This script is written in standard Python 3 and requires no external libraries beyond the built-in math module. It can be executed directly from the command line or imported as a class object (GTOC_Universal_Solver) into larger engineering simulation environments. ⠀ This software is published as a supplemental computational tool to the theoretical framework established in "The General Theory of Correspondence."
