Why does this note show in bolt pretension out file even if in the sample of optistruct training?

NOTE # 6544
Zero force will be applied on pretension sections which are defined but
not explicitly loaded via PRETENSION command. Zero relative deformation
can be enforced there by PRETPRM,INILOAD,ZEROA instead.

    Hello Rachel,
    This note refers to your full model. This is just a note that is shown when you have pretension load in any step load in your model. In case of error or warning, you would receive other messages, not only a note.
    So, this note is given out whenever there is a pretension section defined in the deck. For example, in a model with only normal modes, with no pretension load step, this note would not be given out.
    Thank you very much,
