Abaqus SLM DFLUX Subroutine Simulation Files – Selective Laser Melting

Abaqus SLM DFLUX Subroutine Simulation Files – Selective Laser Melting

This product provides fully functional Abaqus simulation files for selective laser melting (SLM) using the DFLUX subroutine approach. If you’re working on thermal additive manufacturing simulations and need a realistic, proven SLM model in ABAQUS, this package is for you.

Using the Gaussian  heat source, the included Fortran DFLUX subroutine precisely defines heat input in the laser-affected zone. This method is ideal for capturing melt pool dynamics, temperature gradients, and layer-by-layer heat evolution in metallic additive manufacturing.

The model is built in ABAQUS Explicit, enabling thermal transient simulations with fine temporal control and high-speed scanning behavior. You’ll get everything you need to run the simulation, including the .cae model, .inp input file, and .for subroutine code—all clean, commented, and tested.

This SLM simulation package is especially useful for researchers and engineers looking to:

• Simulate thermal cycles during laser scanning

• Understand melt pool formation and cooling behavior

• Study residual stress trends in metal AM

• Customize scan strategies and layer parameters

The files are built for ABAQUS 2024, but compatible .inp files can be adapted for older versions like ABAQUS 2017 or 2020.
