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.
