Hello,
I'm working on the welding simulation using a sequential coupled analysis (thermal+structural).
In my analysis, I use the DFLUX subroutine to simulate the Goldak heat flux of the torch.
I'm trying to simulate the material deposition on the welding bead. According to the papers I've read, I know that I can simulate that thanks to the USDFLD subroutine. With this subroutine, I can change the material properties during the analisys. My goal is to make change the properties of my material when the torch pass along the bead. I mean that before the torch pass on the bead, I use air properties and when the torch passes, I use the bead's properties.
My problem is that I don't really know how to manage that on Abaqus and on my fortran code.
If someone has already done that before or if someone has the knowledge of the USDFLD subroutine, it would be very helpful for me.
Thank you
Rémi
