Abaqus WAAM DFLUX Subroutine Simulation Files – Wire Arc Additive Manufacturing

This Abaqus WAAM DFLUX subroutine simulation package gives you everything you need to model wire arc additive manufacturing (WAAM) with a realistic, moving heat source. Built for Abaqus users who want full control over temperature evolution and layer-by-layer metal deposition, this simulation uses a custom DFLUX subroutine to accurately represent the physics of WAAM.

The model is fully compatible with Abaqus 6.14 and Abaqus 2024, and both CAE and INP formats are included. At the core is the abaqus waam dflux subroutine, written in FORTRAN, that defines a time- and location-dependent heat input to simulate arc movement over multiple layers. The entire simulation is modular and cleanly organized, so you can customize or reuse it in your own projects.

Wire Arc Additive Manufacturing is gaining traction as a scalable, efficient metal AM technique — but simulating it correctly in Abaqus requires careful setup. Many researchers struggle with getting the heat input right or setting up proper layer activation. This product solves that by providing a proven simulation that works out of the box.

Whether you’re working on research, validation, or development, this abaqus waam dflux subroutine simulation lets you investigate:

• Heat distribution in wire arc AM

• Layer activation and thermal accumulation

• Residual stress formation

• Thermal gradients and melting zones

• Temperature evolution across layers

You don’t need to write your own code from scratch. Just compile the included DFLUX file, run the job, and analyze the results.

This package is ideal for:

• PhD researchers in additive manufacturing

• Engineers building custom AM solutions

• Students learning heat-based simulations in Abaqus

• Developers working on multi-pass WAAM validation
