This limitation often forces researchers to compromise between system size and simulation duration, potentially affecting the reliability of results, especially when studying long-term stress effects or large-scale structural changes.

The multiscale nature of stress-induced phenomena in MISH presents an additional hurdle. Stress can induce changes at the atomic level that propagate to macroscopic scales, requiring simulations to bridge vastly different time and length scales. Current MD techniques struggle to efficiently capture these multiscale effects, often necessitating the use of hybrid approaches that combine MD with other computational methods.

Furthermore, the treatment of long-range interactions, particularly in systems with charged species, poses a significant challenge. Accurate representation of electrostatic interactions is crucial for MISH simulations, but traditional methods for handling long-range forces can be computationally expensive and may introduce artifacts in stress-related calculations.

The dynamic nature of stress application and its effects on MISH structure also present difficulties in simulation design. Determining appropriate stress application rates and methods that mimic real-world conditions without introducing artificial dynamics is a delicate balance. This challenge is compounded by the need to maintain proper thermodynamic ensembles during stress application, which can be particularly tricky in non-equilibrium simulations.

Lastly, the validation of MD simulation results for MISH under stress remains a significant challenge. The scarcity of experimental data for direct comparison, especially under extreme stress conditions, makes it difficult to assess the accuracy of simulation predictions. This lack of validation data hampers the refinement of simulation models and the development of more accurate interatomic potentials for MISH systems under stress.
