Node rotation in UEL definition

Hi everyone,

I'm working on UEL and recently I've developed a shell element. To define an element in input file, I'm using counter-clockwise rotation for nodes. When it's just one element everything is good.

When I'm trying to couple bunch of elements in a row together it's giving me some weird results. I realized that if I define different node rotation (to define elements in input file) for elements next to each other it will work. Let's say I wane couple four elements together, Normally I should use counter-clockwise node rotation for all of them but, here I must use counter-clockwise for the first one, clockwise for the second one, counter-clockwise for the third one and clockwise for the fourth one.

Would you please let me know why that is and how I can fix it up?

Best Regards,
