between surfaces ASSEMBLY_M_SURF-1 and ASSEMBLY_S_SURF-1 is causing a 72.434% reduction in the time increment.

The *tie pair (assembly_surf-26-ouhemian,assembly_surf-19) is also used as *contact pair. Remove this *contact pair.

IF BOTH PAIRS ARE *CONTACT PAIRs, THESE TWO PAIRS SHOULD NOT BE SIMULTANEOUSLY PRESENT IN A STEP BECAUSE OF POSSIBLE CONVERGENCE PROBLEMS; USE *MODEL CHANGE,TYPE=CONTACT PAIR TO REMOVE ONE OF THEM.

THEY ARE PAIRED WITH MASTER SURFACES ASSEMBLY_PICKEDSURF74 AND ASSEMBLY PICKEDSURF77 THAT ALSO INTERSECT EACH OTHER.IF BOTH PAIRS ARE *CONTACT PAIRs, THESE TWO PAIRS SHOULD NOT BE SIMULTANEOUSLY PRESENT

The contact pair referencing surfaces assembly_m_surf-1 and assembly_s_surf-1 has at least one instance of a node belonging to both surfaces.

PENETRATION ERROR 325.303E-06 AT NODE CRCP-1.95375 OF CONTACT PAIR (ASSEMBLY_CRCP-UPPER,ASSEMBLY_AC-20-LOW) MAX.

THIS MAY BE DUE TO NONEXISTENT SLAVE OR MASTER SURFACE, OR DUE TO ERRORS WHEN PROCESSING THE *CONTACT PAIR KEYWORD我明明定义了slave surface 和 master surface。

OP=NEW on *CONTACT is ignored when the general contact definition is specified as model data.

Initial contact adjustments for resolving gaps and overclosures when a surface with double-sided facets is paired with any surface having double-sided facets may be incorrect.
