This command is used to construct a ShellNLDKGQ element object accounting for the geometric nonlinearity of large deformation using the updated Lagrangian formula, which is developed based on the ShellDKGQ element.

element ShellNLDKGQ $eleTag $iNode $jNode $kNode $lNode $secTag

---

$eleTag	unique element object tag
$iNode $jNode $kNode $lNode	four nodes defining element boundaries, input in clockwise or counter-clockwise order around the element.
$secTag	tag associated with previously-defined SectionForceDeformation object. Currently can be a PlateFiberSection, a ElasticMembranePlateSection and a LayeredShell section.
