Hi

We experience the problem with the thermal expansion coefficient – the coefficient in the model doesn’t match the numbers from the material database.

We are using X60 steel with 30deg operation temperature and 0deg installation temperature. The properties from the database gives roughly 11*10^(-6) expansion coefficient for 30deg temperature.

In the model, the thermal expansion coefficient is 325*10^(-6).

So the main question is why the thermal expansion coefficient in the model doesn’t match with the value from the database?

And the second question – can we input the thermal expansion manually? How to do it?

Thanks, Polina
