Specifying model attributes

You specify the following model attributes that describe characteristics of the model:

  • Name.

  • Model type.

  • Description of the model.

  • Whether parts and assemblies should be included when you write the model to an input file.

  • Physical constants for the model.

  • If desired, the restart information that will start the analysis using data from a previous analysis. For more information, see Restarting an analysis and Restarting an analysis.

  • Whether the global model that will drive the submodel boundary conditions or loads. You can also specify that the global model is a shell driving a solid submodel. For more information, see Submodeling.

  • Whether constraints, connector section assignments, and surface-to-surface contact and self-contact interactions defined in the initial step will be copied to the current working model when you create model instances from this model. For more information, see Working with model instances.

What is an Abaqus/CAE model?
Manipulating models within a model database

  1. From the main menu bar, display the Edit Model Attributes dialog box using one of the following methods:

    • To specify model attributes in a new model, select ModelCreate from the main menu bar.

    • To specify model attributes in an existing model, select ModelEdit Attributesmodel name from the main menu bar.

  2. If you are creating a new model, select the model type:

    • Select Standard & Explicit (default) to create a model for an Abaqus/Standard or an Abaqus/Explicit analysis.

    • Select Electromagnetic to create a model for an electromagnetic analysis.

    You cannot change the model type in an existing model.

  3. If desired, enter or revise a description for the model.

    1. Click in the Edit Model Attributes dialog box.

      The model description editor appears.

    2. In the model description editor, type information that you want to record about the model.
    3. Click OK to store the description and to close the model description editor.

    The description that you enter is saved in the model database and is written above the header of the input file when you submit the model for analysis; the description is not written to the output database. For more information, see Adding descriptions to your Abaqus/CAE model.

  4. If you want Abaqus/CAE to write input files without parts and assemblies, toggle on Do not use parts and assemblies in input files. For more information about this option, see Writing input files without parts and assemblies.

  5. In the Physical Constants portion of the dialog box, do the following:

    • To specify surface emissivity and radiation conditions in heat transfer analyses, enter values for the absolute zero temperature and the Stefan-Boltzmann constant.

    • To specify the universal gas constant, enter a value in the Universal gas constant field.

    • To identity the type of incident wave loading for an incident wave interaction in acoustic analyses, toggle on Specify acoustic wave formulation, click the arrow to the right of the text field, and select the formulation.

      • Select Scattered wave to obtain the scattered wave field solution that will be produced by incident wave loading.

      • Select Total wave to obtain the total acoustic pressure wave solution.

  6. If desired, click the Restart tab to specify restart information that will start the analysis using data from a previous analysis. Toggle on Read data from job and do the following:

    • Type the name of the job from which Abaqus/CAE will read the restart information.

    • Type the name of the step from which Abaqus/CAE will restart the analysis.

    • Choose the increment, interval, iteration, or cycle of the step from which Abaqus/CAE will restart the analysis.

  7. If desired, click the Submodel tab and do the following:

    • Toggle on Read data from job and enter the name of the output database from which the global solution will be used to drive the submodel boundary conditions or loads. You can also enter the name of a results file, if an output database is not available.

    • Specify whether the submodel will be a solid that is driven by a global shell model.

    For more information, see Creating a submodel.

  8. By default, constraints, connector section assignments, and surface-to-surface contact and self-contact interactions defined in the initial step (along with their contact interaction properties) will be copied to the current working model when you create model instances from this model. To change this behavior, click the Model Instances tab and toggle off the objects that you do not want copied.

  9. Click OK to save your data and to close the dialog box.
