Curved Shell Formulation

Hi,

My structure is composed of Quad4 shell elements. I have used thin and thick element formulation separately in hypermesh to compare their results. However, I see that their results are not as accurate as curved shell formulation used in ANSYS. I would like to aske that is there any card available in HM which is a similar card with curved shell formulation (KEYOPT(5)) used in ANSYS.
