Well here are steps for simple analysis. First of all i'm not any professional but maybe this will help you.
This is the bracket i'm going to use.
Open the part file and then go to Tools>>addins and check the SolidWorks Simulation there and click OK.
Now under simulation tab click Study advisor and New study.
Enter any name and keep the default type of study (i.e. Static). Click OK.
Now click Apply material.
Select the material and click apply and close.
Under Fixture advisor choose Fixed geometry.
The fixture property manager will show. Here we have to define the faces which will remain fix during the loading condition.
Select the holes and click OK. These holes will be fixed by bolts.
Now select External Loads and then Force.
Select the face under load and enter the value of load. Click OK.
Now click Run under simulation tab. Some meshing screen and solver will process and after done the deformed part will show.
This is the analysis output screen. You can change the different option under results for desired output.
