This work presents a simulation-based investigation of electromagnetic field asymmetry in asymmetric resonant cavity systems, motivated by phenomenological models of emergent vacuum-response effects under nonequilibrium conditions. Building upon prior theoretical and quantitative prediction frameworks, reduced-order finite-difference simulations are used to compute spatial energy-density distributions within representative resonator geometries. These distributions are used to evaluate the asymmetry parameter A, which quantifies imbalances in electromagnetic energy density. The results show that realistic asymmetric configurations can produce nonzero asymmetry factors on the order of A ~ 0.1, consistent with values assumed in prior phenomenological models. These findings provide initial numerical support for the physical plausibility of geometry-induced energy-density asymmetry and its potential role in generating measurable stress imbalances. Estimated force magnitudes derived from the computed asymmetry values remain in the nanonewton range under representative field conditions, providing a concrete experimental target for validation. The simulations are intentionally reduced-order and illustrative rather than full finite-element or full-wave electromagnetic solutions. Their purpose is to bridge the gap between theoretical models and physically realizable systems, motivating further investigation using high-fidelity numerical methods and precision experimental testing. Overall, this work contributes to the development of a falsifiable framework for exploring nonequilibrium electromagnetic stress effects in asymmetric resonator systems.
