Coefficient of Thermal Expansion — Isotropic
Enter a value or the name of a thermal expansion coefficient function. You can type a value or right-click the property text box to define the coefficient of thermal expansion as a function of temperature, or assign a parameter as appropriate.
 
* For hyperelastic materials, you cannot define the coefficient of thermal expansion as a function of temperature.
This property is optional, but you should enter a value if you plan to place a thermal load on the model.
