A neutral data format designed for graphics exchange between computer-aided design (CAD) systems. Using Abaqus/CAE, you can import IGES-format parts, and you can export parts in IGES format. In addition, you can import and export a sketch from an IGES file.

An interval of an analysis step.

A condition you prescribe to define the initial value of a solution, state, or field variable such as stress or temperature. You can define initial conditions by creating predefined fields in the Load module.

An ASCII file that is read and processed by Abaqus/Standard, Abaqus/Explicit, or Abaqus/CFD and contains keywords and data that define your model. When you submit a job for analysis using Abaqus/CAE, it generates an input file based on the model you have defined. If necessary, you can modify the input file generated by Abaqus/CAE using the Keywords Editor. In addition, you can import Abaqus/Standard or Abaqus/Explicit input files into Abaqus/CAE; Abaqus/CAE translates the options and data lines in the imported input file into a new Abaqus/CAE model.

A capability in Abaqus/Design that allows you to create an input file in which parameters are used in place of input quantities. The parameters are evaluated according to their definition and are substituted for the parametrized quantities before an analysis is performed by Abaqus/Standard or Abaqus/Explicit. See also keyword parameter to learn how keyword parameters are used in an Abaqus input file.

See part instance.

Step-dependent objects that define how bodies or regions in a model act with each other or with their surrounding environment; examples include contact, kinematic relationships associated with mechanical connectors, and thermal constraints such as convection or radiation boundary conditions. Interactions also establish dependencies between fields such as coupled thermomechanical, coupled pore fluid-mechanical, and coupled thermal-electrical effects. In Abaqus/CAE an elastic foundation is also considered a form of interaction.

An Abaqus/CAE module used to define interactions between regions of a model or between a region of a model and its surroundings.

• Chapter 15, “The Interaction module,” of the Abaqus/CAE User's Guide

A collection of data that are necessary to define certain types of interactions completely.
