Hi Adeleine,

Check the coefficient of thermal expansion for all materials and make sure you use the correct units for temperature when you are entering a CTE value.

Check that all the materials and bodies are assigned the same reference/Environment temperature.

Try running the Static Structural model with a Thermal Condition and assign a 1 degree temperature increase to all bodies.  For example, if the reference temperature is 20 C, assign a Temperature of 21 C to all bodies and see if you get a reasonable thermal expansion and reasonable stress values.

Regards,
Peter
