Automatic single point constraint option. AUTOSPC specifies the action to take when singularities exist in the stiffness matrix ([Kff]). Setting AUTOSPC to ON means that singularities will be constrained automatically. Setting AUTOSPC to OFF means that singularities will not be constrained. If AUTOSPC is ON, identified singularities with a ratio smaller than STIFFRATIOTOL (default = 1.0E-8) will be automatically constrained with single-point constraints. See STIFFRATIOTOL and PRGPST. |
