MatAbaAutoRel: A MATLAB–Abaqus framework for automated reliability analysis

Probabilistic and reliability analyses utilizing finite element software are frequently constrained by manual model creation and result extraction. This study presents an open-source, MATLAB-based framework integrated with Abaqus that automates randomized model generation through Monte Carlo simulation, performs analyses, and retrieves target results via a lightweight Python script in noGUI mode. The modular tool reduces user intervention and facilitates automated variations in geometry, material properties, and loading conditions. This framework enables rapid model generation and result extraction for hundreds of analyses in seconds, significantly reducing manual effort and potential human error. • Open-source MATLAB–Abaqus framework automates finite element reliability analysis. • Generates hundreds of randomized Abaqus models and extracts results in seconds. • Minimizes manual work and errors for large-scale probabilistic reliability analyses. • Methodology readily adapts to other FE software for advanced nonlinear analysis.
