Finally, the quantum computing results are fed back to the multi-agent system module, which can simulate the interaction of microcracks and their impact on macroscopic fracture behavior, achieving seamless connection from quantum computing to macroscopic simulation, and enhancing the comprehensive analysis capability of the entire system.
