FEA on a Welded Tray

I'm putting my hands in the Simulation and trying to design a tray. I've done the modeling part but not clear as how to do the FEA of it. Please look at the attached picture which give the details on boundary parameters. Material would be Plain Carbon Steel.

Can any one help on how I should be setting my study to get the desired result and accordingly change my design.
