SPC - Altair
Included in a single point constraint (SPC or SPC1) Declared a dependent degree-of-freedom on any RBAR, RBE1, RBE2, or RROD entry. Declared a dependent degree-of-freedom on an MPC set referenced in the same subcase. Single-point forces of constraint are recovered during stress data recovery. Up to twelve single-point constraints may be defined ...

NLPARM - Altair
The NLPARM Bulk Data Entry is selected by the Subcase Information command NLPARM = option. Each subcase for which nonlinear analysis is desired requires an NLPARM command. The solution method for quasi-static nonlinear analysis (ANALYSIS = NLSTAT) is full Newton. The stiffness matrix is updated at each iteration.

CBUSH - Altair
A CBUSH element, referencing a PBUSH property with a single stiffness term, is equivalent to a CELAS1 or CELAS2 element, only when the elements have zero length. A non-zero length CBUSH assumes rigid body connections from the connection points, GA and GB, to the spring-damper location, as defined either by S or the OCID and Si fields.
