Part two is conforming to the shape of Part One in a realistic ...

WebbWhen a contact pair uses the tied contact formulation, Abaqus/Standard uses the undeformed configuration of the model to determine which slave nodes are within the adjustment zone (see Adjusting the surfaces in a contact pair), accounting for any shell or membrane thickness by default. Abaqus/Standard then adjusts these slave nodes' …
