Create post-processing expressions

1. Open the Create Expression dialog box:When you click Reduction , the Create Expression dialog box appears automatically.In the Reduction or Multiple Reduction dialog box, in the Expression Manager group, click Add Expression .

2. Specify the result component to reduce:Select the results set, iteration or load case, and result type.For models containing laminates, specify the ply number.For models containing shell elements, specify the shell element layer.

3. From the Component list, select the result component or derived quantity.

4. If you have specified an element-nodal tensor result component, and your model contains shell or beam elements, in the Location group, from the Shell Section or Beam Section list, select a stress recovery point.

5. If you have specified an element-nodal tensor result component, and your model contains beam elements, you can derive complete stresses and strains from element forces and beam geometry using the options in the Beam Result group. See Beam stresses.

6. If you have specified an elemental or element-nodal result, in the Nodal Combination group, specify how to combine values at nodes. Choose from None, Average Across, or Sum.

7. If your model includes results in complex format, in the Complex Options group, choose the complex part from the list.

8. In the Results Options group, specify the coordinate system and units used to express the reduced value. See Coordinate systems in post-processing for more information.

9. Click Create Expression.

10. Repeat these steps to create additional expressions. Click Close when complete.
