primaryAxisVector: A sequence of Floats specifying the vector that defines the direction of the primary axis of the discrete orientation.

Returns:

A MaterialOrientation object.

PlyStackPlot#

class PlyStackPlot[source]#

The PlyStackPlot object is used to plot the stacking of plies in a composite layup or in a composite shell section.

PropertyAssembly#

class PropertyAssembly[source]#

An Assembly object is a container for instances of parts. The Assembly object has no constructor command. Abaqus creates the rootAssembly member when a Model object is created.

Notes

This object can be accessed by:

import assembly
mdb.models[name].rootAssembly

Methods

SectionAssignment(region, sectionName[, ...])

This method creates a SectionAssignment object.

Parameters:

region: A Set object specifying the region to which the section is assigned.
sectionName: A String specifying the name of the section.
thicknessAssignment: A SymbolicConstant specifying section thickness assignment method. Possible values are FROM_SECTION and FROM_GEOMETRY. The default value is FROM_SECTION.
offset: A Float specifying the offset of the shell section. The default value is 0.0.
offsetType: A SymbolicConstant specifying the method used to define the shell offset. If offsetType is set to OFFSET_FIELD the offsetField must have a value. Possible values are SINGLE_VALUE, MIDDLE_SURFACE, TOP_SURFACE, BOTTOM_SURFACE, FROM_GEOMETRY, and OFFSET_FIELD. The default value is SINGLE_VALUE.
offsetField: A String specifying the name of the field specifying the offset. The default value is “”.

Returns:

A SectionAssignment object.

SectionAssignment#

class SectionAssignment(region: Set, sectionName: str, thicknessAssignment: SymbolicConstantType = 'FROM_SECTION', offset: float = 0, offsetType: SymbolicConstantType = 'SINGLE_VALUE', offsetField: str = '')[source]#

The SectionAssignment object is used to specify a section assignment on an assembly or part. Section assignments on the assembly are limited to connector elements only.

Notes

This object can be accessed by:

import section
mdb.models[name].parts[name].sectionAssignments[i]
import assembly
mdb.models[name].rootAssembly.sectionAssignments[i]
import odbAccess

session.odbs[name].rootAssembly.sectionAssignments[i]
session.odbs[name].steps[name].frames[i].fieldOutputs[name].values[i].instance.sectionAssignments[i]

Attributes:

suppressed: Boolean: A Boolean specifying whether the section assignment is suppressed or not. The default value is OFF.

Methods

`getVertices`()	This method is only valid for connector section assignments.
`resume`()	This method resumes the section assignment that was previously suppressed.
`setValues`()	This method modifies the SectionAssignment object.
`suppress`()	This method suppresses the section assignment.

getVertices()[source]#

This method is only valid for connector section assignments. This method returns a sequence consisting of tuples of coordinates of the connector’s endpoints.

Returns:

A python:sequence of tuples of floats.

Raises:

An exception is thrown if getVertices() is called on any section assignment except

connector section assignment.: This method is valid only for connector section assignments.

resume()[source]#: This method resumes the section assignment that was previously suppressed.

setValues()[source]#: This method modifies the SectionAssignment object.

suppress()[source]#: This method suppresses the section assignment.
