Enter values for the coefficients of thermal expansion. You can define this property or you can assign a parameter to the property. Type in a value or right-click on the property text box to assign a parameter as appropriate.

For orthotropic material properties, enter values for:

These values represent the thermal expansion coefficient in each of the three principal material directions of the model.

For transversely isotropic material properties, enter the following two values for coefficients of thermal expansion:

These values represent the thermal expansion coefficient in each of the three principal material directions of the model, with equal values in directions 2 and 3.

You should enter values for this property if you plan to place a thermal load on the model.
