13.8 RigidBody object

The RigidBody object constrains all the degrees of freedom on the specified regions to the degree of freedom of its associated reference point.

The RigidBody object is derived from the Constraint object.

13.8.1 RigidBody(...)

This method creates a RigidBody object.

Path
mdb.models[name].RigidBody

Required arguments

name

A String specifying the constraint repository key.

refPointRegion

A Region object specifying the reference point.

Optional arguments

bodyRegion

None or a Region object specifying the elements constrained to the movement of the reference point. The default value is None.

tieRegion

None or a Region object specifying the nodes tied to the movement of the reference point. The default value is None.

pinRegion

None or a Region object specifying the nodes pinned to the movement of the reference point. The default value is None.

surfaceRegion

None or a Region object specifying the analytic surface constrained to the movement of the reference point. The default value is None.

refPointAtCOM

A Boolean specifying whether the analysis product should recompute the reference point position to be at the center of mass. The default value is OFF.

isothermal

A Boolean specifying whether the temperature degree of freedom should be constrained. The default value is OFF.

Return value

A RigidBody object.

Exceptions

None.


13.8.2 setValues(...)

This method modifies the RigidBody object.

Required arguments

None.

Optional arguments

The optional arguments to setValues are the same as the arguments to the RigidBody method, except for the name argument.

Return value

None

Exceptions

None.


13.8.3  Members

The RigidBody object has members with the same names and descriptions as the arguments to the RigidBody method.

In addition, the RigidBody object has the following member:

suppressed

A Boolean specifying whether the constraint is suppressed or not. The default value is OFF.
