The PointMassInertia object defines point masses and point rotary inertia on a part or an assembly region.
The PointMassInertia object is derived from the Inertia object.
import part mdb.models[name].parts[name].engineeringFeatures.inertias[name] import assembly mdb.models[name].rootAssembly.engineeringFeatures.inertias[name]
This method creates a PointMassInertia object.
mdb.models[name].parts[name].engineeringFeatures.PointMassInertia mdb.models[name].rootAssembly.engineeringFeatures.PointMassInertia
Required arguments
A String specifying the repository key.
A Region object specifying the region to which the mass or rotary inertia is applied.
Optional arguments
A Float specifying the mass magnitude for isotropic mass. This parameter cannot be specified when anisotropic mass terms are specified. The default value is 0.0.
A Float specifying the mass in the 1-direction for anisotropic mass. This parameter cannot be specified when isotropic mass is also specified. The default value is 0.0.
A Float specifying the mass in the 2-direction for anisotropic mass. This parameter cannot be specified when isotropic mass is also specified. The default value is 0.0.
A Float specifying the mass in the 3-direction for anisotropic mass. This parameter cannot be specified when isotropic mass is also specified. The default value is 0.0.
A Float specifying the rotary inertia about the local 1-axis,
. The default value is 0.0.
A Float specifying the rotary inertia about the local 2-axis,
. The default value is 0.0.
A Float specifying the rotary inertia about the local 3-axis,
. The default value is 0.0.
A Float specifying the product of inertia,
. The default value is 0.0.
A Float specifying the product of inertia,
. The default value is 0.0.
A Float specifying the product of inertia,
. The default value is 0.0.
None or a DatumCsys object specifying the local coordinate system for the anisotropic mass terms (when specified), and the rotary inertia (when specified). If localCsys=None, the anisotropic mass and rotary inertia data are defined in the global coordinate system. The default value is None.
A Float specifying the alpha damping magnitude. The default value is 0.0.
This argument applies only to Abaqus/Standard analyses.
A Float specifying the composite damping magnitude. The default value is 0.0.
This argument applies only to Abaqus/Standard analyses.
Return value
A PointMassInertia object.
Exceptions
This method modifies the PointMassInertia object.
Required arguments
Optional arguments
The optional arguments to setValues are the same as the arguments to the PointMassInertia method, except for the name argument.
Return value
Exceptions
The PointMassInertia object has members with the same names and descriptions as the arguments to the PointMassInertia method.
In addition, the PointMassInertia object has the following member:
A Boolean specifying whether the inertia is suppressed or not. The default value is OFF.
