Weld Modeling

I have modeled a steel wide flange with rib plates. The result I am interested in are the weld stresses.

I have modeled the weld as 3d but there are parameters that I can't input.

Is it better to model the weld in 3d? If there are better ways to do this, let me know.

Again, I am only interested on the weld stresses.

I am attaching my hm model and the *.out file.
