The ContactExp object defines the contact domain and associated properties during contact in an Abaqus/Explicit analysis.
The ContactExp object is derived from the Interaction object.
import interaction mdb.models[name].interactions[name]
This method creates a ContactExp object.
mdb.models[name].ContactExp
Required arguments
A String specifying the repository key.
A String specifying the name of the step in which this contact interaction is created.
Optional arguments
A Boolean specifying whether the contacting surface pair consists of all exterior faces, shell edges, beam segments, analytical rigid surfaces, and when applicable, Eulerian material surfaces.
A Boolean specifying whether surface smoothing (geometric correction) is automatically applied to all eligible surfaces. The default value is ON.
A RegionPairs object specifying the domain pairs included in contact.
A RegionPairs object specifying the domain pairs excluded from contact.
A ContactPropertyAssignment object specifying the contact property assignments in the contact domain.
A SurfaceThicknessAssignment object specifying the surface thickness assignments in the contact domain.
A SurfaceOffsetAssignment object specifying the surface offset fraction assignments in the contact domain.
A SurfaceFeatureAssignment object specifying the surface feature angle assignments in the contact domain.
A SmoothingAssignment object specifying the surface smoothing assignments in the contact domain.
A MasterSlaveAssignment object specifying the master-slave assignments in the contact domain.
Return value
A ContactExp object.

Required arguments
A String specifying the repository key.
A String specifying the name of the step in which this contact interaction is created.
Optional arguments

A sequence of pairs of Region objects or SymbolicConstants that specifies the surface pairs in contact. Possible values of the SymbolicConstants are ALLSTAR and SELF. This argument is valid only when useAllstar=OFF.
A sequence of pairs of Region objects or SymbolicConstants that specifies the surface pairs excluded from contact. Possible values of the SymbolicConstants are ALLSTAR and SELF.
A sequence of tuples specifying the properties assigned to each surface pair. Each tuple contains three entries:
A Region object or the SymbolicConstant GLOBAL.
A Region object or the SymbolicConstant SELF.
A String specifying an InteractionProperty object associated with this pair of regions.
A sequence of tuples specifying the surface thickness assignments in the contact domain. Each tuple contains three entries:
A region object or the SymbolicConstant GLOBAL specifying the surface to which the surface thickness is assigned.
A Float or a SymbolicConstant specifying the overriding thickness value to be used in the contact definition. Possible values of the SymbolicConstant are ORIGINAL or THINNING.
A Float specifying a scale factor that multiplies the thickness value specified in the second entry.
A sequence of tuples specifying the surface offset fraction assignments in the contact domain. Each tuple contains two entries:
A region object or the SymbolicConstant GLOBAL specifying the surface to which the surface offset fraction is assigned.
A Float or a SymbolicConstant specifying the offset fraction value to be used in the contact definition. Possible values of the SymbolicConstant are ORIGINAL, SPOS, or SNEG.
A sequence of tuples specifying the surface feature angle assignments in the contact domain. Each tuple contains two entries:
A region object or the SymbolicConstant GLOBAL specifying the surface to which the surface feature angle is assigned.
A Float or a SymbolicConstant specifying the overriding feature angle value to be used in the contact definition. Possible values of the SymbolicConstant are PERIMETER, ALL, PICKED, or NONE.
A sequence of tuples specifying the surface smoothing assignments in the contact domain. Each tuple contains two entries:
A region object specifying the surface to which the smoothing option is assigned.
A SymbolicConstant specifying the smoothing option to be used in the contact definition. Possible values of the SymbolicConstant are NONE, REVOLUTION, SPHERICAL, or TOROIDAL.
A sequence of tuples specifying pure master-slave assignments in the contact domain. Each tuple contains three entries:
A region object or the SymbolicConstant GLOBAL specifying the first surface that defines the master-slave assignment.
A region object specifying the second surface in the master-slave assignment definition.
A SymbolicConstant specifying the status of the first surface. Possible values are MASTER and SLAVE.
Return value
A ContactExp object.
