Hi, in CAESAR II 5.1 and 5.2 the material in subject, above 426°C, has allowable but hasn't thermal expansion coefficient.
When I run error checker, CAESAR II tells "temperature is outside the allowed range for this material" even if this limit should be up to 593°C for grade 1 and above 593°C for grade 2.
Please, can You explain me what's the problem and how can I solve it?
Thanks.
