The ExplicitDynamicsStep object is used to perform a dynamic stress/displacement analysis using explicit integration in Abaqus/Explicit.
The ExplicitDynamicsStep object is derived from the AnalysisStep object.
import step mdb.models[name].steps[name]
This method creates an ExplicitDynamicsStep object.
mdb.models[name].ExplicitDynamicsStep
Required arguments
A String specifying the repository key.
A String specifying the name of the previous step. The new step appears after this step in the list of analysis steps.
Optional arguments
A String specifying a description of the new step. The default value is an empty string.
A Float specifying the total time period for the step. The default value is 1.0.
A Boolean specifying whether geometric nonlinearities should be accounted for during the step. The default value is ON.
A Boolean specifying that an adiabatic stress analysis is to be performed. The default value is OFF.
A SymbolicConstant specifying the time incrementation method to be used. Possible values are AUTOMATIC_GLOBAL, AUTOMATIC_EBE, FIXED_USER_DEFINED_INC, and FIXED_EBE. The default value is AUTOMATIC_GLOBAL.
None or a Float specifying the maximum time increment. If there is no upper limit, maxIncrement=None. This argument is required only when timeIncrementationMethod=AUTOMATIC_GLOBAL or AUTOMATIC_EBE. The default value is None.
A Float specifying the factor that is used to scale the time increment. This argument is required only when timeIncrementationMethod=AUTOMATIC_GLOBAL, AUTOMATIC_EBE, or FIXED_EBE. The default value is 1.0.
A MassScalingArray object specifying mass scaling controls. The default value is PREVIOUS_STEP.
A Float specifying the linear bulk viscosity parameter,
. The default value is 0.06.
A Float specifying the quadratic bulk viscosity parameter,
. The default value is 1.2.
None or a Float specifying the user-defined time increment. This argument is required only when timeIncrementationMethod=FIXED_USER_DEFINED_INC. The default value is None.
A Boolean specifying whether to retain attributes from an existing step with the same name. The default value is False.
Return value
An ExplicitDynamicsStep object.
Exceptions
RangeError.
This method modifies the ExplicitDynamicsStep object.
Required arguments
Optional arguments
The optional arguments to setValues are the same as the arguments to the ExplicitDynamicsStep method, except for the name, previous, and maintainAttributes arguments.
Return value
Exceptions
RangeError.
