I've never tried to do a simulation before, just be aware of that ... maybe someone else can verify but I don't think I missed anything.
I hope this will help.
Open the part, go to the Office Products tab, click on SolidWorks Simulation.
A new tab called Simulation will appear, click on it, Study Advisor, New Study.
As I already applied the material to the part you won't need to.
You can do the the following instructions from the tab or you can follow what I did.
You have to have a fixture in your part so I fixed one end and doubled the force on the other, it'll give you the same results.
Right click on Fixtures and choose Fixed Geometry.
Select an end (highlighted in blue), then the green check mark.
Right Click on External Loads and choose Pressure.
Select the other end, choose the measuring unit (N/mm^2) which is MPa put a value of 60 and check Reverse direction then the green check mark.
Right click on Study and choose Properties.
Choose the settings that suits you form the Adaptive tab.
I got an error with H-Adaptive and P-Adaptive but I think it's just something wrong with my software.
Right click on Mesh and choose Mesh and Run.
Few seconds and you'll see the results on screen, you can now generate a report; show the stress, displacement, strain ... etc.
