Hi
I want also to move a laser source on a sheet as you know a subroutine(Dflux)Needs, Is it possible to tell me how can I write it and how can I import it to ABAQUS? I've read Abaqus help but I have some problems, therefore I think it's better to run a real example. Do you have an example for running in abaqus.
Thanks
Mehrdad

I have solved one part of my problem using DFLUX subroutine for the temperature distribution in the a simple plate (moving with time having guass distribution). Now, I am facing problem in coupling the this thermal analysis with static stress analysis. When I use the my thermal results (.odb) as predefined field, it seems working, but I dont get any stresses in the plate. I changed the eleemmnt type to 3D stress (C3D4)from heat transfer (DC3D4).
