PARAM, AUTOSPRT

Bulk Data Entry Activate inertia relief and auto-support degree-of-freedom generation.

Parameter Values Description
AUTOSPRT <1, 0> This parameter applies to residual vector calculation in inertia relief analysis.
1 (Default)
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.
0
SUPORT dofs are automatically generated using the 6 geometric rigid body modes.
