This study presents an advanced computational framework that enhances the efficiency and accuracy of the traditional Finite Element Method (FEM) through the integration of three innovative techniques: (1) Pattern-Aware Vectorized Assembly algorithm to eliminate iterative loops, (2) Graph Neural Network (GNN) model for intelligent mesh adaptation, and (3) Parallel computing acceleration using Graphics Processing Units (GPUs). The methodology was validated on three benchmark problems including fluid flow and nonlinear structural analysis. Results demonstrated an improvement in accuracy up to three orders of magnitude (from 1.5×10⁻³ to 2.1×10⁻⁶) and a reduction in computation time by up to 93% compared to conventional methods. Newton-Raphson iterations decreased from 15 to 6 iterations, with a 26% reduction in memory consumption. The GNN model exhibited strong generalization capability, reducing total degrees of freedom by 40% while maintaining accuracy. These findings demonstrate the viability of integrating artificial intelligence with high-performance computing for solving complex engineering problems.
