Goldak DFLUX Arc Welding Simulation Files for Abaqus

This Goldak DFLUX arc welding simulation Abaqus package gives you a complete, ready-to-run model built in Abaqus with a moving double ellipsoid heat source. The setup uses a custom-written DFLUX subroutine in Fortran to simulate realistic weld pool geometry and deep heat penetration — ideal for arc welding simulations where spatial accuracy and heat distribution are critical.

The model is based on the Goldak double ellipsoid formulation, widely used in welding research and thermal field analysis. You’ll walk through the full process — from clean model setup to writing the subroutine — exactly as shown in the popular tutorial Arc Welding Simulation in Abaqus: Goldak DFLUX Subroutine.

Tested in Abaqus 2024 and 6.14-2, this package includes all necessary files to simulate, modify, and extend the model to your own geometry or welding path. This is the cleanest implementation available — no missing parameters, no blurred code, no hacks.
