slippage/tolerance between threaded hole and a hole on simulation

Hi guys,

I have a threaded hole 30 mm in diameter on one plate steel a-36 and a 35 mm hole on another plate steel 4140. When I try running a thermal simulation both materials expand at different rates. The holes can be adjusted for a 2 1/2 thousandths of an inch which will cover a lot of stress generated. My problem is that I do not know if solidworks can account for this? When I fix both holes (concentric) I see stresses much higher than the materials resistance which I think is because the materials do not have any tolerance to move and starts generating stresses right away. delta temperature is 200F.
