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