Getting high thermal stress in 2D axisymmetric model

[McT178]

I am trying to learn to use Algor at a new company by recreating some old FEAs for practice. The problem is that I only have PDFs to work with so I cannot see how the FEAs were developed. I have managed to successfully recreate some temperature distributions, but I always end up being about 20% high when determining the thermal stresses. Does anyone have any suggestions to why this would happen? Thanks.

I realized that my above question may be too vague, so I will clarify some. I think what I need to know is how to get the linearized stress from Algor. Thanks again.
