ExpInitialization object

The ExpInitialization object is used in conjunction with ContactExp in Abaqus/Explicit analyses to specify contact initialization data.

The ExpInitialization object is derived from the ContactInitialization object.

ExpInitialization(...)

This method creates an ExpInitialization object.

Path

mdb.models[name].ExpInitialization

Required arguments

name

A String specifying the contact initialization repository key.

Optional arguments

overclosureType

A SymbolicConstant specifying the type of overclosure to be defined. Possible values are ADJUST, INTERFERENCE, and CLEARANCE. The default value is ADJUST.

interferenceDistance

None or a Float specifying the interference distance. This argument is valid only when overclosureType=INTERFERENCE. The default value is None.

clearanceDistance

None or a Float specifying the initial clearance distance. This argument is valid only when overclosureType=CLEARANCE and must be specified in that case. The default value is None.

openingTolerance

None or a Float specifying the distance tolerance within which initial openings will undergo strain-free adjustments. This argument is not valid when overclosureType=INTERFERENCE unless a value has been specified for interferenceDistance. The default value is None.

overclosureTolerance

None or a Float specifying the distance tolerance within which initial overclosures will undergo strain-free adjustments. The default value is None.

adjustNodalCoords

A Boolean specifying whether to resolve clearances/overclosures by adjusting the nodal coordinates without creating strain in the model. adjustNodalCoords=True can be used only for clearances/overclosures defined in the first step of an analysis. The default value is True.

secondaryNodesetName

A String specifying the name of the node set containing the secondary nodes to be included in the initial clearance specification. This argument is not valid when overclosureType=INTERFERENCE and if openingTolerance or overclosureTolerance is specified. The default value is None.

stepFraction

A Float specifying the fraction of the step time (between 0.0 and 1.0) in which the interference fit has to be solved. The default value is 1.0. This argument is valid only when overclosureType=INTERFERENCE.

Return value

An ExpInitialization object.

Exceptions

RangeError.

setValues(...)

This method modifies the ExpInitialization object.

Required arguments

None.

Optional arguments

The optional arguments to setValues are the same as the arguments to the ExpInitialization method, except for the name argument.

Return value

None.

Exceptions

RangeError.

Members

The ExpInitialization object has members with the same names and descriptions as the arguments to the ExpInitialization method.
