The thermal expansion coefficient corresponds to "A" in °C^(-1) or K^(-1). For this error, you have to define your material differently:

Then, what do you want to do exactly ? Because your temperature is not well defined and I think that you have to add more constraints or add convection and ambient temperature if you want this.

thankyou

just a tip:

these questions are related to 'Altair Products' session, if you prefere, post them in that session in order to get better audience. And you can add tags such as 'OptiStruct'. More people will check these if they're in the right bucket.
