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

element('ShellNLDKGT', eleTag, *eleNodes, secTag)
eleTag (int) unique element object tag
eleNodes (list (int)) a list of three element nodes in clockwise or counter-clockwise order around the element
secTag (int) tag associated with previously-defined SectionForceDeformation object. currently can be a 'PlateFiberSection', a 'ElasticMembranePlateSection' and a 'LayeredShell' section
