The GeometryShellSection object defines the properties of a geometry shell section. The GeometryShellSection object has no explicit constructor and no methods. The GeometryShellSection object is an abstract base type.
The GeometryShellSection object is derived from the ShellSection object.

Required arguments
Optional arguments
A String specifying the name of the AnalyticalField or DiscreteField object used to define the thickness of the shell elements at each node. The nodalThicknessField argument applies only when thicknessType=NODAL_ANALYTICAL_FIELD or thicknessType=NODAL_DISCRETE_FIELD. The default value is an empty string.
A String specifying the name of the AnalyticalField or DiscreteField object used to define the thickness of the shell elements. The thicknessField argument applies only when thicknessType=ANALYTICAL_FIELD or thicknessType=DISCRETE_FIELD. The default value is an empty string.
A SymbolicConstant specifying the distribution used for defining the thickness of the elements. Possible values are UNIFORM, ANALYTICAL_FIELD, DISCRETE_FIELD, NODAL_ANALYTICAL_FIELD, and NODAL_DISCRETE_FIELD. The default value is UNIFORM.
A Boolean specifying whether the shell section properties are specified by the user prior to the analysis (ON) or integrated during the analysis (OFF). The default value is OFF.
A SymbolicConstant specifying whether to use the default value for the Poisson's ratio. Possible values are:
The default value is DEFAULT.
DEFAULT, specifying that the default value for the Poisson's ratio is 0.5 in an Abaqus/Standard analysis and is obtained from the material definition in an Abaqus/Explicit analysis.
VALUE, specifying that the Poisson's ratio used in the analysis is the value provided in poisson.
A Float specifying the Poisson's ratio. Possible values are –1.0
poisson
A SymbolicConstant specifying the shell section integration rule. Possible values are SIMPSON and GAUSS. The default value is SIMPSON.
A SymbolicConstant specifying the mode used for temperature and field variable input across the section thickness. Possible values are GRADIENT and POINTWISE. The default value is GRADIENT.
None or an Int specifying the number of temperature points to be input. This argument is valid only when temperature=POINTWISE. The default value is None.
None or a Float specifying the effective thickness modulus. This argument is relevant only for continuum shells and must be used in conjunction with the argument poisson. The default value is None.
A Boolean specifying whether or not to use the value of density. The default value is OFF.
A Float specifying the value of density to apply to this section. The default value is 0.0.
Return value
A GeometryShellSection object.
