# CNTLCK

Bulk Data Entry Defines parameters for the contact (S2S and N2S) lock in the preloaded Linear Analysis subcase.

This entry should be referenced by CNTLCK Subcase Information Entry in the preloaded Nonlinear Static Analysis subcase (small and large displacement analysis are supported). Then the contact lock is applied to the preloaded Linear Analysis subcase which is preloaded by the corresponding Nonlinear Static Analysis subcase that contains the CNTLCK Subcase Information Entry.

CNTLCK ID PARAM VALUE

The following continuation line (beginning with the CNTINT flag) is used to define another set of lock parameters, which locally overrides the set of parameters above, and applies locally on a specific contact interface (CTID). It can be repeated as required.

VALUE The value assigned to PARAM.

CNTINT Defines the start of a continuation line used to specify another set of interference parameters, which overrides the set of parameters defined above, for a specific contact interface (CTID). It can be repeated as required.
CTID Contact interface identification number.
