create_spotweld(nodeid1, nodeid2)

Define massless spot welds between non-contiguous nodal pairs.

Parameters:

nodeid1int

ID for the first node.

nodeid2int

ID for the second node.

Returns:

bool

True when successful, False when failed.

create_cnrb(nodeset)

Create a nodal rigid body, which is a rigid body that consists of defined nodes.

Parameters:

nodesetNodeSet

Node set that defines the rigid body.

Returns:

bool

True when successful, False when failed.

create_joint_spherical(nodes, relative_penalty_stiffness=1.0, damping_scale_factor=1.0)

Create a joint between two rigid bodies.

Parameters:

nodeslist

List of nodes for creating the joint.

relative_penalty_stiffnessint, optional

Relative penalty stiffness. The default is 1.0.

damping_scale_factorint, optional

Damping scale factor on the default damping value. The default is 1.0.

merge_two_rigid_bodies(lead_rigidbody=0, constrained_rigidbody=0)

Merge two rigid bodies.

One rigid body, called the constrained rigid body, is merged into another rigid body, called the lead rigid body.

Parameters:

lead_rigidbodyint, optional

Part ID for the lead rigid body. The default is 0.

constrained_rigidbodyint

Part ID for the constrained rigid body. The default is 0.

create()

Create a constraint.
