COGConstraint (hwx.inspire.core)¶
Create the Center of Gravity Constraint (COG) of supplied parts.
Use the Center of Gravity Constraint (COG) to apply, reposition, and set upper and lower bounds for a center of gravity constraint. COG constraints are used to limit the position of the center of gravity while running a topology optimization.

Attribute Details¶
active : Bool¶
Returns or sets the object activeness.
Setting this on or off sets all children. Setting to True sets all the parents active too.
color : Color¶
The color assigned to the boundary condition.
connectionRadius : Double (units=”length”)¶
The search radius for the boundary condition.
connectionType : Enum (rigid, flexible)¶
The type of the connection. Valid choices are:
rigid
flexible
direction : Direction¶
The direction of vector the boundary condition.
distributed : Bool¶
Returns whether the applied boundary condition is distributed or not.
Boundary conditions applied across the entire feature area (for faces) or length (for edges) are distributed and at a single point boundary conditions are non-distributed.
features : Attribute¶
The list of features to which the boundary condition is applied.
localToPart : Bool¶
Returns or sets ‘Rotate with part’.
It makes boundary condition not to rotate or rotate along with its associated part.
location : Location (units=”length”)¶
The location of the boundary condition.
mode : Enum (direction, components)¶
Specifies the mode of the boundary condition.
Valid choices are:
direction
components
name : Attribute¶
Returns or sets the name of the object.
It can be any text string, including spaces, although it’s best to avoid using the following characters: ” ‘ * ? and $.
While these characters are allowed, they could create difficulties when you export the model to other applications.
part : Attribute¶
Returns the part on which the entity is applied graphically.
parts : Attribute¶
The list of parts on which the boundary condition is applied.
visible : Bool¶
Determines whether the boundary condition is visible or not.
Property Details¶
- property bounds¶
A list of the lower and upper bound values in X, Y and Z directions for COG during optimization, defaults to [-0.1, 0.1, -0.1, 0.1, -0.1, 0.1]. If None is specified in a position (e.g. [None, -0.1, None, None, None, None]) then this direction is inactive.
- property position¶
A Matrix44 of X, Y and Z directions of COG and the current position, defaults to math.Matrix44(origin=getCenterOfGravity(ents))
Method Details¶
- classmethod getClass(cls, className)¶
Returns the class of the object.
It can be simple or qualified (with namespace). If the name is simple, we prepend the cls.namespace.
- param className
The class name.
- type className
Union[Part, Occurrence, Named..]
- returns
The class for the specified className.
- rtype
Union[Part, Occurrence, Named..]
- classmethod importLoads(cls, csvFile)¶
Imports boundary conditions to the active model from a csv file.
- param csvFile
Csv file name containing all the BC information.
- type csvFile
str
- returns
List of error msgs that happened during import of all the boundary conditions.
- rtype
list
- __new__(cls, ents, **kwds)¶
Create the Center of Gravity Constraint (COG) of supplied parts.
- param ents
List of selected parts for which COG constraint is

To set other attributes to the bc. e.g.: color =”red”.
- returns
Return the created Center of Gravity Constraint (COG).

COG
- destroy(self)¶
Delete the object removing it from the model.
The object may come back due to an undo/redo.

- getChild(self, name=None, recursive=False, **kwds)¶
Returns the child of the object which matches the specified unique name.
- param name
The name of the child object.
- type name
str
- param recursive

- type recursive
bool
- param **kwds
Additional keyword arguments to match attributes of the object.
- returns
The child object which satisfies the specified filters.
- rtype

- param recursive
- type recursive
bool
- param **kwds
Filter objects using isa.
- returns
set[Named]
- getReferences(self, recursive=False, **kwds)¶
Get objects this object references through a Reference attribute.
- param recursive

- isa(self, type=None, filter=None, name=None, wildcard=None, **kwds)¶
Determines if the object matches the specified settings or not.
- param type
The type of the object.

Union[Part, Assembly, Contact..]
- param filter
Return value of specified callback method.
- type filter
method
- param name
Name that matches exactly with object name.
- type name
str
- param wildcard
A pattern to match exactly with the object name.
- type wildcard
str
- param **kwds
Additional keyword arguments to match other attributes.
- returns
True, if a match is found, otherwise False.
- rtype
bool
- modelPositions(self)¶
Forces all objects to return the original model positions instead of the current analysis positions.
Useful when defining draw methods on GeneralObjects where behaviour is different while animating.
- updatePosition(self, m44)¶
Sets the design space positions of all the inspire parts to their position in the current analysis frame.
