Hi,


Sorry I was not making myself clear. I meant in the “Engineering Data" in a "Transient Thermal Analysis" in Workbench, there is no thermal expansion coefficient defined. It means the thermal expansion coefficient is not needed for this analysis. 


In the materials overview in Mechanical (shown in your image), it will show all the material properties of that material, whether or not it can be used in this simulation. 


To bring more peace to your mind, you can refer to the equations in the theory manual of a transient thermal analysis (for some reason I cannot insert an image, but please refer to this website: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v194/ans_thry/thy_heat1.html.


If you want to incorporate contraction/residual stress effect, you can do a static structural analysis. You can pass the result of a steady state thermal analysis or transient thermal to a static structural analysis. 


Please let me know if you have more questions. 


Regards,


Wenlong
