Introduction to UMAT Subroutine in Abaqus
In many engineering projects, the built-in material models in Abaqus are not enough for capturing complex material behavior. This is where user-defined material subroutines come into play. Abaqus allows advanced users to write their own material model through a User MATerial subroutine, commonly known as UMAT. In simple terms, a UMAT is a piece of […]

Life Assessment and Creep Damage Analysis of Welded Components
Life Assessment and Continuum Damage Creep Analysis of Welded Components By: Saman Hosseini – Expert in creep welding simulation, fatigue, and FFS Level 3 assessments. Introduction Imagine a high-pressure steam pipe in a power plant, with countless welded joints, all enduring red-hot temperatures for decades. How do engineers predict whether those welds will survive or […]
Master Python Scripting in Abaqus: Automate Your CAE Workflows
If you’re still setting up every simulation by hand, you’re missing out on huge time savings. Modern CAE tools let Python scripts orchestrate the whole workflow – geometry, mesh, solver setup and post-processing – as one seamless pipeline. In fact, “CAE automation is the process of streamlining simulation workflows—geometry creation, meshing, solver setup, and post-processing […]
Fatigue Life Prediction in FEA – A Comprehensive Guide (ANSYS, Abaqus, fe-safe & More)
Introduction Fatigue failure is one of the most common causes of unexpected breakdowns in engineering structures subjected to cyclic loading. Even when stresses are well below a material’s yield or ultimate strength, repeated load cycles can initiate small cracks that grow over time, eventually leading to catastrophic fracture. Predicting fatigue life (the number of cycles […]
Additive Manufacturing & Welding Simulation in FEA: A Comprehensive Guide
Additive manufacturing (often called 3D printing) and traditional welding are both processes that involve melting and fusing material. These processes offer incredible possibilities (from printing intricate medical implants to welding critical oil-and-gas pipelines), but they also introduce challenges like residual stresses, distortion/warping, and complex thermal histories. Finite Element Analysis (FEA) has become an indispensable tool […]
Abaqus Training & Consultancy: Mastering FEA from Basics to Advanced Worldwide
Introduction Picture a young engineer facing a complex Finite Element Analysis (FEA) problem in Abaqus – unsure how to proceed, deadlines looming. Now imagine that same engineer after expert training and mentoring: confidently simulating, interpreting results, and delivering innovations ahead of schedule. This transformation is the power of comprehensive Abaqus training and consultancy. Whether you’re […]
Predictive Corrosion Modeling in Pipes and Vessels Using AI and Finite Element Methods
Revolutionizing Corrosion Simulation in Pipes and Vessels: Leveraging AI and FEM Software for Accurate Predictive Maintenance Corrosion is one of the most challenging issues in engineering, especially when considering its long-term impact on the integrity of critical infrastructure, such as pipes, pressure vessels, and marine structures. The need for advanced methods to simulate corrosion and […]
Fitness for Service (FFS) in Asset Integrity
The Role of Fitness-for-Service (FFS) in Asset Integrity Fitness-for-Service (FFS) analysis is a structured engineering approach to determine if equipment with flaws or damage can continue to operate safely and reliably. It is a crucial part of asset integrity management, especially in high-risk sectors like oil & gas, power generation, and manufacturing. Over an asset’s […]
What is the Best FEA Software in 2025
What is the Best FEA Software in 2025 Finite Element Analysis (FEA) software has become a cornerstone of modern engineering, allowing designers to virtually test how products and structures behave under various forces and conditions. By breaking complex structures into smaller “finite” elements and simulating physical phenomena (like stress, heat, or fluid flow) on each […]
