Strain Output ( LE vs E)

Hi


I need your help again. Thanks in advanced.

I tried to output regular strain of E11, E22, E33 like below. why I only have LE in visualization. Then I removed LE from the list and I still only get LE output. I don't understand it. I am doing hydraulic fracturing using cohesive element. My understanding is LE should be close to E in most of conditions. Am I correct? Thank you so much for your help.

*Element Output, directions=YES
FLVEL, LE, S, SDEG,PFOPEN,E
