I admit this one is a little strange, but bear with me.
If you run the Simulation on this part, and view the Displacement result, you will get a rainbow.
I'm not sure what SolidWorks version this is saved as, but the file is from 2007, so it's at least that old. This should work with Simulation Xpress.
