How would you set up a simulation of a simple wall standard and bracket?

I am looking to do a static simulation for a series of sheet metal brackets with mounting teeth installed on a wall standard with a series of rectangular cuts. 

I am currently trying to make a simple assembly making sure there is no interference, fixing the standard in space, and using "no penetration" contact sets for the parts that would interact when a load is applied.

I don't use simulation often so I am trying different mesh styles (curvature vs standard) and densities. My results from test to test have have precise displacement, but the stresses are inconsistent. Sometimes the material is yielding, sometimes it isn't. Sometimes the materials stress is spread out, sometimes solidworks decides that all the stress is in one area. I'm also plagued by "PRE1 program not completed successfully" errors after making minor tweaks. I sware the errors come and go with identical setups. Not sure if study files saved in the root folder causes issues when re-simulating.

Ideally, I'd like the simulation to act as if the bracket feels weight, bends, and then interacts with the standard as it would in reality..


Any wisdom on what setup would work?

At this weight, the stresses seem to high and concentrated.
