Abaqus FEA Simulation

Abaqus/CAE interface showing a welding simulation error message ("Too many attempts at this increment") alongside a corrected model with adjusted material properties and stabilization controls, demonstrating the troubleshooting process. Option 2 (Diagnostic Flowchart): A detailed troubleshooting flowchart for Abaqus welding simulations, mapping symptoms (e.g., "zero pivot warning") to specific causes (e.g., unconstrained rigid body motion) and solutions (e.g., contact stabilization), with relevant .msg file excerpts. Option 3 (Before/After Convergence): Side-by-side comparison of a welding simulation: Left panel shows a diverged model with distorted mesh and error log; Right panel shows a stable analysis with smooth temperature gradients and converged residual stress contours after applying fixes. Option 4 (Parameter Adjustment Guide): Visual guide highlighting key Abaqus parameters to adjust for convergence: material yield floor at high temperature, contact stabilization settings, time increment controls, and hourglass energy
