PARAM, AUTOMSET

Parameter

Values

Description

AUTOMSET

<YES, NO>

Default = NO

Defaults

1.	The default is typically NO when the parameter is not present in the deck (see Note 4).

2.	Cannot be specified in the input deck without a value. OptiStruct will error out in this case.

If YES, the dependent degrees-of-freedom of rigid elements may be converted to independent degrees-of-freedom when conversion is necessary for the model to run.

If NO, the above conversion will not be performed. The model may not run when multiple constraint equations reference the same dependent degree-of-freedom more than once.

Note

1.	This parameter can be used if the dependent degree-of-freedom (DOF) of a rigid element is SPC’ed, or if it is a dependent DOF of another constraint equation (MPC equation or another rigid element).

2.	AUTOMSET cannot be used if Direct Matrix Input (DMIG) generation is performed using the Static Condensation method (Component Mode Synthesis (CMSMETH entry) is not used).

3.	Sufficient number of independent degrees of freedom that can be converted into dependent degrees of freedom, while eliminating double dependency, should exist in the model.

4.	PARAM, AUTOMSET is set automatically to YES only if RBODY entries or MPC-based TIE contact are present in the model.
