Surf 154 element

[Sarikahirpara]

Hello,

I am doing a mid surface analysis using shell181 element. I want to use surf 154 element also but i dont know how to use it or how to apply it to my model. Pls help
Is there any way to select the element type of our choice??

Thanks

At least in Workbench if you have a model (either shell or solid) and
surface load (force, pressure, ...) applied, SURF154 elements are used
automatically. You can check from solve.out which elements are used.
