What is the meaning of PRJGRAD?

PRJGRAD is occurred in sensitivity analysis results in frd document when keywords * FEASIBLE DIRECTION is used. But I didn’t find any explanation of this word. Can anyone give me an explanation? Thanks.

Where exactly have you seen this ? Can you share the file ? I submitted the exemplary input files from CalculiX test examples library (opt1 and opt3) and there’s no such output variable available in GraphiX.

Thanks for your reply. PRJGRAD is in the output file(.frd). And I think its full name is projective gradient and means the combination of sensitivity of objective function and constraints w.r.t design variables. And you can find it in the opt1.frd. Thanks.
