Create an Analysis Step

Define a step that allows boundary conditions and output requests to be added to the model.

Nonlinear solution controls tailored for Simulation Composite Analysis are also specified, allowing for a robust, converged solution.

Here, a step is defined that allows boundary conditions and output requests to be added to the model.

1. Switch to the Step module.
2. Create a new Static, General step (Step > Create) named Load_Step.
3. Set the Initial and Maximum Increment size to 0.01 on the Incrementation tab of the Edit Step dialog box.
4. Click OK.

To achieve robust convergence when using Simulation Composite Analysis, the solution controls must be modified from their default state.

5. Open the General Solution Controls dialog box by clicking Other > General Solution Controls > Edit > Load_Step from the main toolbar, ignore the warning, and click the Specify radio button.
6. From the Time Incrementation tab enter 1000 for the values of both I₀ and I_R .
7. Click the first tab labeled 'more' and enter 1000 for the values of I_P , I_C , I_L , and I_S . Set I_T to 10.
   Note: Increasing these specific values will ensure Abaqus can take full advantage of the improved convergence characteristics provided by Simulation Composite Analysis.
8. Click OK.
