Simulating 3D crack growth Abaqus XFEM simulation is one of the most powerful (and often misunderstood) techniques in fracture mechanics. If you’ve ever attempted it and failed—or didn’t know where to begin—this guide is for you. Simulating fracture is one…

If you’ve ever struggled to simulate realistic welding in Abaqus—especially using the Goldak double ellipsoid heat source—you’re not alone. Most tutorials skip critical steps or hide the actual subroutine code. This post walks you through the entire Abaqus Goldak DFLUX…

If you’re trying to apply complex or sinusoidal loads in Abaqus, you’re probably wondering: Is this going to require hours of coding?Well, it turns out the Abaqus DLOAD subroutine isn’t just capable—it’s surprisingly easy. In this post (and video), I…

Abaqus DFLUX Welding Simulation has always been a hot topic! If you’ve ever searched for a clear, complete guide to running an Abaqus DFLUX welding simulation, chances are you were disappointed. Most tutorials either skip the critical steps or hide…

Welding residual stress Abaqus simulations can be much simpler than you think. In this tutorial, you’ll learn how to predict residual stress without coding, using only thermal results from a previous simulation. This is the best method I’ve found to…

Performing a Welding Simulation in Abaqus Without DFLUX dramatically simplifies the modeling workflow, removes the need for Fortran subroutines, and accelerates your simulation setup.This detailed guide walks you through exactly how to simulate welding heat transfer and residual stress inside…

Learn how to link Abaqus 2024 with the Fortran Compiler and Microsoft Visual Studio correctly because is essential for successfully running user subroutines such as UMAT and DFLUX. A minor mistake in the compatibility check or environment setup can prevent…
