Hello Praveen,


Ansys Workbench will use the CTE value that is closest to -14 C (i.e. the CTE for 22 C) in this case. However, be sure to understand the difference between secant CTE and instantaneous CTE while defining the material properties. See Section 2.1.3 in: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v201/en/ans_thry/thy_str1.html%23structempdep
