thermal stress analysis : TEMPADD command

Dear community,

I want to compute the stress from a thermal load on my assembly. I only want to do a "simple" static analysis using only the thermal expansion coefficient.

I have defined different temperature area through the TEMP command (I make sur to put only one temperature value by grid). Then, I set up the "missing" temperature grid through the TEMPD command.

Now I want to group all these loads into one TEMPADD command but I cannot find it despite the FAQ Altair (FAQ - TEMPADD Defines a static load as a linear combination of the TEMP or TEMPD Bulk Data Entry. (altair.com)) cf. screenshot

Do you know why I cannot find the TEMPADD command ? (Hyperworks version 2022.3)

Best regards,

Aurélien
