Thermal Expansion Uniform Temperature Distribution

I have been getting more questions lately about thermal stress in Inventor Nastran, so I've created 2 videos to share to outline the process. This video covers the process to set up a thermal stress all from within a linear static analysis - which is the approach when the part or assembly is all at the same elevated or reduced temperature (uniform temperature). The second video (thermal expansion - thermal gradient) will cover the process to use when there is a gradient.
