ID |
An associated NLPARM entry identification number. No default (Integer > 0) |
TYPE |
Constraint type Default = CRIS (CRIS, RIKS, or MRIKS) |
| 1. | The NLPCI bulk data entry is selected by the Subcase Information command NLPARM = option. There must also be an NLPARM entry with the same ID. It is only used in geometric nonlinear (quasi-)static analysis (ANALYSIS = NLGEOM). |
| 2. | NLPCI is implemented for Nastran compatibility and imported if present. Only the fields ID, TYPE are interpreted. With NLPCI present, the default for NLPARMX, SACC will be reset to RIKS. TYPE will be translated into CTYPE; all other entries are set to default. A warning will be issued. NLPCI and NLPARMX cannot be used simultaneously. It is recommended to remove NLPCI and use NLPARMX with the appropriate definitions. |
| 3. | This card is an unsupported bulk data entry in HyperMesh. |
