Hi jousefm,
thanks for your effort → the problem is fixed.
I took the CTE data from the citation, calculated the length change due to the temperature and from these data the averaged CTE. The simulation matches the expected values. I put some graphs in these post. The reference temperature Tref=293.15K.
CTE of Aluminum
Calculated expansion (the integral of the CTE)
The averaged CTE used.
Maybe this is helpfull for somebody else.
You can find the CTE Table in the project cited above.
Best regards to all
