He opened a file titled GlobalSolver_v9_FINAL.m. His fingers danced across the keys, refining the meshing parameters and tightening the boundary conditions. He wasn't just solving for displacement anymore; he was chasing the "hot" spots—those crimson zones of high stress that predicted catastrophic failure.
