Surface based COHESIVE BEHAVIOR cannot be used for contact pair interactions. See the surface interaction named INTPROP-CO.

Once a pair of surfaces is used for *tie, it cannot be used again for *contact pair and vice versa.

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.

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。

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.

Please remove the contact field output for the contact pair in question, or split the node-based surface into separate surfaces each spanning just one instance

cohesive性质用general contact和surface to surface（explicit）都报错，surface base cohesive contact只能用于bonded contact？

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.

以下是status文件相关信息***WARNING: Master surface ASSEMBLY_SURF-CU-3 of contact pair # 5 contains facets with out-of-plane warping of at least 20.000 degrees in increment 22480.

abaqus 中当使用 硬接触 功能中的 Allow separation after contact（不勾选）时，出现下列警告，请教下要怎么解决At least one non-blank surface must be specified for contact surface interactions referencing NO SEPARATION surface behavior

IN A STEP BECAUSE OF POSSIBLE CONVERGENCE PROBLEMS; USE *MODEL CHANGE,TYPE=CONTACT PAIR TO REMOVE ONE OF THEM.

for the out-of-plane thickness of the corresponding surface under *surface interaction.
