Abaqus Welding Simulation Masterclass: No Code To Subroutine

Master welding simulation in Abaqus CAE using finite element analysis—start with no-code FEA, end with DFLUX subroutines

What you'll learn

Simulate welding heat input in Abaqus using moving heat source techniques without any coding or subroutines.

Apply element reactivation in Abaqus to simulate progressive weld bead formation during thermal analysis.

Implement Gaussian and Goldak DFLUX subroutines to model laser and arc welding processes with precision.

Predict and visualize post-welding residual stresses using step-by-step simulation workflows in Abaqus.

Requirements

Basic knowledge of finite element analysis (FEA) is recommended. You’ll need Abaqus CAE installed (student or commercial version). No coding experience required for most sections—subroutines are explained step-by-step.

Description

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.
