Abaqus DFLUX Welding Simulation Files

This is the most complete Abaqus DFLUX Welding Simulation Files setup using the DFLUX subroutine available — built from scratch and ready to run. You’ll learn how to create the entire model in Abaqus, write the full DFLUX subroutine in FORTRAN, and simulate a moving Gaussian heat source step by step to model a realistic welding process.

Unlike other models, this simulation package includes everything: the full code, the complete thermal setup, and detailed guidance on how DFLUX works. Whether you’re simulating TIG, laser, or arc welding, this method gives you full control over heat input, welding travel path, and thermal gradients — without relying on surface flux shortcuts.

Originally built in Abaqus 2024 and fully tested in Abaqus 6.14-2, this welding model is designed for engineers, researchers, and graduate students who want precision thermal control in their welding simulations. The files are clean, editable, and tutorial-backed — perfect for learning, modifying, and publishing.
