Interaction

Fields

name: String, default = ""

Unique name of the interaction algorithm definition that will be used to reference the object by other objects
guide_group_names: Vector of String, default = []

Reference to the mesh surface(s) for the guide. (required)
follower_group_names: Vector of String, default = []

Reference to the mesh surface(s) for the follower. (required)
group_names: Vector of String, default = []

Reference to the mesh surface(s).

This limits the scope of detection algorithm to the provided group names and automatically chooses guide and follower pairs from them.

This option cannot be used with guide_group_names or follower_group_names.
interaction_tolerance: String, default = ""

(Glue only) Tolerance used to include points that are not on a guide surface but are at a distance of the guide surface that is within the interaction_tolerance.

It determines whether two surfaces are close enough to be considered touching and default is 0.0.

(Contact only) Tolerance used to specify a penetration limit for unbonded contact surfaces used in interference fits and surface correction steps of initial penetration correction analysis

or used in resolve initial penetration step of contact initialization so that if a follower surface initially penetrates the guide by more than this limit then it is not brought back to aligned contact.

This tolerance is absolute. Default is to trigger the solver to automatically compute the interaction tolerance equal to 10% or the geometric length scale of the contact surfaces involved in the interaction
two_way_interaction: Bool, default = false

Boolean specifying if two way contact is activated or not for this interaction pair

Two way interaction will automatically create a dual interaction object in which the guide and follower surfaces are reversed with respect to the current interaction object
interaction_type: InteractionType, default = SurfaceToSurface

Type of the interaction between the surfaces

By default, this is set to node to surface
general_interaction_detection: Bool, default = false

An option to activate general interaction detection between surfaces

This option means that every exterior surface of any part can interact with every other exterior surface of another part (no self-interaction for now)

If general detection is activated, then no other interaction can be defined for now, and only a single contact model can be defined

This only works with contact for now and not with glue
released: Bool, default = false

This is a boolean that specifies that this interaction will be ignored

That means that this interaction will not be called during the interaction detection phase

Therefore, this interaction cannot be used as part of a glue and or contact model
