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)
unique element object tag
a list of three element nodes in clockwise or counter-clockwise order around the element
tag associated with previously-defined SectionForceDeformation object. currently can be a
