Element normal

Recommended Posts

Need some information regarding element normal.
As per my knowledge element normal represents the positive side of shell elements but when I display both color as well as vector display opposite nature observed. Element normal representing negative side(i.e. red)
I defined thickness in negative direction(i.e. SNEG) and it is offsetting the elements outwards that means HM is following color display convention. Is it HM bug or something I am missing?

Thank you for update.

If red is positive (which means vector representing face is positive) then why upon defining SNEG in property element thickness offset in outward/positive direction? Refer picture shared earlier
