Thermal Expansion Thermal Gradient

I have been getting more questions lately about thermal stress in Inventor Nastran, so I created 2 videos to share to outline the process. This video cover the set up when there will be a thermal gradient in the part or assembly - running a thermal analysis first and then bringing those temperatures in to stress analysis. See also the video 'Thermal Expansion Uniform Temperature Distribution' for the process when there is no temperature gradient.
