Why Resolving Convergence Issues Matters

In nonlinear finite element simulations, convergence issues are a frequent barrier to obtaining accurate and reliable results. These problems commonly arise in models involving contact, nonlinear materials, or unstable geometries. Understanding and resolving these challenges is essential for reducing simulation time, increasing robustness, and improving overall project efficiency.
