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 inAbaqusthe right way? Whether you’re a student, researcher, or professional engineer, this course will teach you how to perform advancedfinite element welding simulationsstep by step—starting from a no-code setup and progressing tocustom DFLUX subroutines.

This is the most complete and structuredAbaqus welding simulation masterclassavailable online. It covers the full workflow, from beginner-friendly heat source modeling to advancedthermal simulations using user subroutines.

You’ll start with a clean, code-free model inAbaqus CAE, learning how to simulate amoving heat sourcewithout writing any FORTRAN or using complex inputs. Then, you’ll use theelement reactivation techniqueto 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 forlaser welding simulations

Goldak double ellipsoid– widely used inarc welding simulations

You’ll implement and run these subroutines inAbaqus Standard, with full explanations of every line of code.

Finally, the course shows you how topredict and visualize residual stressesafter welding using a realistic thermal-mechanical setup.
