The HomogeneousShellSection object defines the properties of a shell section.
The HomogeneousShellSection object is derived from the GeometryShellSection object.
sectionApi.sections()[name]
This method creates a HomogeneousShellSection object.

An odb_String specifying the repository key.
An odb_String specifying the name of the section material.
Optional arguments
A Double specifying the thickness of the section. The thickness argument applies only when thicknessType="UNIFORM". The default value is 0.0.
An Int specifying the number of integration points to be used through the section. Possible values are numIntPts
0. The default value is 5.
To use the default settings of the analysis products, set numIntPts to 5 if integrationRule="SIMPSON" or set numIntPts to 7 if integrationRule="GAUSS".
An odb_String 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 (true) or integrated during the analysis (false). The default value is false.
An odb_String 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 Double specifying the Poisson's ratio. Possible values are –1.0
poisson
An odb_String specifying the shell section integration rule. Possible values are "SIMPSON" and "GAUSS". The default value is "SIMPSON".
An odb_String 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".
An odb_String specifying the mechanical idealization used for the section calculations. This member is only applicable when preIntegrate is set to true. Possible values are "NO_IDEALIZATION", "SMEAR_ALL_LAYERS", "MEMBRANE", and "BENDING". The default value is "NO_IDEALIZATION".
The string "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".
The string "NONE" or a Double 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 false.
A Double specifying the value of density to apply to this section. The default value is 0.0.
An odb_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.
An odb_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.
Return value
A HomogeneousShellSection object.
Exceptions
The HomogeneousShellSection object has members with the same names and descriptions as the arguments to the HomogeneousShellSection method.
In addition, the HomogeneousShellSection object can have the following members:
odb_RebarLayers rebarLayers() const; odb_TransverseShearShell transverseShear() const;
A RebarLayers object specifying reinforcement properties.
A TransverseShearShell object specifying the transverse shear stiffness properties.
