Comments

Preprocess:

Allows the user to define 3 lines with any comment he desires.

Postprocess:

In Postprocess, comments can be automatically generated by GiD every time a result view is selected, like the second line shown in the above image.

Or it can be defined by the user. Following parameters fields can be used:
%an - analysis name
%sv - step value in analysis
%sn - step number in analysis
%ns - total number of steps value in analysis
%vt - result visualization type
%vf - vector factor
%rn - result name
%cn - component name
%da - deformation used analysis
%ds - deformation used step value
%dr - deformation used result
%df - deformation used factor
%tcl() - evaluate a tcl expression, for instance "Correct step value: %tcl( expr %sv * 2.5 + 3)"

To define comments behaviour go to Preferences window → Postprocess → Legends and comments, and in the shown panel, look for ‘Comments options’:
