Abaqus Welding simulation Masterclass: No Code to Subroutine

About this course

Looking to simulate welding in Abaqus the right way? Whether you’re a student, researcher, or professional engineer, this course will teach you how to perform advanced finite element welding simulations step by step—starting from a no-code setup and progressing to custom DFLUX subroutines.This is the most complete and structured Abaqus welding simulation masterclass available online. It covers the full workflow, from beginner-friendly heat source modeling to advanced thermal simulations using user subroutines.You’ll start with a clean, code-free model in Abaqus CAE, learning how to simulate a moving heat source without writing any FORTRAN or using complex inputs. Then, you’ll use the element reactivation technique to simulate the stepwise deposition of weld material, just like real welding sequences.After that, you’ll take your skills to the next level with two powerful DFLUX-based methods: Gaussian heat input – ideal for laser welding simulationsGoldak double ellipsoid – widely used in arc welding simulationsYou’ll implement and run these subroutines in Abaqus Standard, with full explanations of every line of code.Finally, the course shows you how to predict and visualize residual stresses after welding using a realistic thermal-mechanical setup. What’s Included:Full model setup in Abaqus CAESubroutine walkthroughs (Gaussian & Goldak)Downloadable input files for each lessonClear explanations of FEA principles, heat transfer, and thermal boundary conditionsHigh-quality voice, visuals, and editing—no filler, no fluff You Will Learn
