Any NEi Nastran tension only shell element experience?

Any NEi Nastran tension only shell element experience?

(OP)
I was wondering if anybody has experience using the NEi Nastran tension only shell element. It has been a common challenge at the aerospace companies I have worked at to properly idealize the buckled behavior of thin aircraft skins and panels in a finite element model, especially at the vehicle level for internal loads. There are solutions that range from using CSHEAR elements all the way up to full nonlinear analysis with a fine mesh, and of course a number of things in between. It seems like a quasi-nonlinear approach like a tension only shell might be a reasonable compromise of analysis fidelity and computational cost...
