Description

FZERO

<Real>

Default = 0.1

This parameter defines the maximum frequency for a rigid body mode for the Lanczos eigensolver. That is all eigenmodes with frequency at or below this cutoff will be regarded as rigid body modes in the inertia relief analysis.

Note:

To set the rigid body mode cutoff eigenvalue for the AMSES and AMLS eigensolvers, use PARAM, RBMEIG.
