The RegionPairs object stores the domain pair definition for ContactExp and ContactStd objects. The RegionPairs object has no constructor or members.
import interaction mdb.models[name].interactions[name].excludedPairs mdb.models[name].interactions[name].includedPairs
This method allows addition and removal of domain pairs in a given step.
Required argument
A String specifying the name of the step in which the region pair assignments are to be modified.
Optional arguments
A Boolean specifying whether the contacting surface pair consists of all exterior faces and -- in an Abaqus/Explicit analysis -- analytical rigid surfaces, shell edges, and beam segments in the model.
A sequence of pairs of region objects or SymbolicConstants that specify the surface pairs to add to the included pairs of the ContactExp or ContactStd object in the given step. Possible values of the SymbolicConstants are GLOBAL and SELF. When used with a ContactExp object, the second parameter of each pair can also be a string that references an Eulerian material surface.
