Field

Contents

COID

Unique coupler identification number.

(Integer > 0)

JIDi

Joint identification numbers.

No default (Integer > 0)

TYPEi

Type.

No default (TRA or ROT) – See comment 3.

RATIOi

Coefficients of the coupler constraint equation.

Default = 1.0 (Real)

Comments

1.COUPLERs are only valid in a multi-body solution sequence.
2.At least JID1 and JID2 need to be defined.
3.The type is optional if the Joint is revolute or translation. But if the joint is cylindrical, the type should be set to TRA to denote that the translational motion is coupled or ROT to specify that the rotational motion is coupled.
