Description

AUTOSPRT

<1, 0>

Default = 1

This parameter applies to residual vector calculation in inertia relief analysis.

If 1, rigid body modes from the eigenvalue analysis (PARAM,FZERO defines cut-off for determination of rigid body modes) are used to automatically generate SUPORT dofs.

If 0, SUPORT dofs are automatically generated using the 6 geometric rigid body modes.
