Very basic question? Entering Residual stress

Hello,
I'm trying to enter a residual stress inside a thin film. In model builder I go under "solid mechanics (solid)" >> "Linear elastic material 1" >> "Initial Stress and strain" and I enter -250e10 for the row 1 column 1 and row 2 column 2 entry under "initial stress". When I simulate the stress in the x direction at room temperature, with a reference temperature at room temperature, I get a stress close to 0 Pa. Perhaps I'm misunderstanding something very basic but I would expect it to be -250e10. What am I missing?

Seems like I have to put in a fixed boundary condition and that solves the problem. Is this typically how it's done?
