Restarting after adding more analysis steps to the model

The most common use of the restart capability is to analyze your model and then add one or more steps to the model and continue the analysis. This section describes an example of this usage.

Assume that you have done the following:

  • Created a model called Model-A that has two analysis steps, Step-1 and Step-2.

  • Used the Edit Restart Requests dialog box in the Step module to output the restart information at the end of each step.

  • Created a job called Job-A that uses Model-A.

  • Analyzed the model.

After studying the results of the analysis, you decide to add another step, Step-3, to the model. The restart capability allows you to compute the results for Step-3 without having to repeat the computations for Step-1 and Step-2. The following steps describe a recommended procedure to follow:

  1. Copy Model-A to a new model, say Model-A-restart, and make Model-A-restart the current model.

  2. Add the new Step-3 to Model-A-restart.

  3. Add new prescribed conditions (loads, boundary conditions, interactions, fields, or output requests) in Step-3, or modify the prescribed conditions propagated from Step-2.

  4. From the main menu bar, select ModelEdit AttributesModel-A-restart. From the Edit Model Attributes dialog box that appears, do the following:

    • Enter Job-A as the job from which the restart data will be read.

    • Set the restart location:

      • Enter Step-2 to indicate the step from which the restart data will be read.

      • Choose Restart from the end of the step. Step-3 will continue the analysis after the end of Step-2.

  5. Copy Job-A to a new job, say Job-A-restart, that uses Model-A-restart.

  6. From the main menu bar, select JobEditJob-A-restart. From the Edit Job dialog box that appears, choose a job type of Restart.

  7. Submit Job-A-restart for analysis.
