For small deformation, volumetric CTE = 3*linear CTE, and Areal CTE = 2*linear CTE. Now, I collected temperature dependent Linear CTE inputed as part of my mateiral property. When I modelling for solid cubical or plate, shall I also change the CTE according to the shape of the object?

CTE is the thermal property of the material and it will not change on the basis of the shape of the object. Like for volumetric CTE = 3 Linear CTE. Here the CTE is the same but for easy calculation, we have denoted the term 3 *Linear CTE as volumetric thermal expansion. CTE is the property of the material and it will not depend upon the shape and size of the material.

Thanks for your prompt response!
By definition, the CTE in Workbench is linear expansion data or else?

It's a linear thermal expansion.
