History Definition

  ABAQUS History data is used to specify what happens to the model and will take the form of a number of ABAQUS steps, one step per FEMGEN loadcase in ascending order of loadcase number. Each step is divided into four parts: Step Definition, Procedure Definition, Load and Boundary Conditions, and Results Output Control. This chapter details Step Definitions, Procedure Definitions, and Results Output Control; Load and Boundary Conditions are detailed in the chapter 7. Refer to the ABAQUS User's Manual for more detailed information on the fundamental concepts involved in ABAQUS history definitions.

The interface program places the following comment cards at the start of the history definition section of the ABAQUS input file.

A typical step definition would be as follows:

*STEP, PERTURBATION                    (Step Definition)
*STATIC                                (Procedure Definition)
