Edit and manage post-processing expressions

The Expression Manager group in the Scalar Reduction and Multiple Reduction dialog boxes provides a number of tools to help you edit and manage post-processing expressions.

Note:

Post-processing expressions are available only when combining and manipulating results. You cannot access post-processing expressions using the standard Expressions dialog box.

Rename an expression

By default, the software assigns names to post-processing expressions. These are abbreviated forms of the result component. For example, X displacement is represented by the expression DX, and von Mises stress is named SVM. You may find it helpful to give these expressions more meaningful names.

To rename a post-processing expression, click its cell in the Expression Manager table. Type the new name and press Enter.

Insert an expression into a formula

To quickly insert an expression name into a formula, right-click a row in the Expression Manager table and choose Insert.

Alternatively, type the expression name into the Formula field, or type just a few characters and choose the expression name from the list of matching names.

Delete an expression

Click a row in the Expression Manager table to select it, and then click Delete Expression .

In the Multiple Reduction dialog box, you can quickly delete all post-processing expressions from the Expression Manager table. Click Delete all .

Edit an expression

To edit an existing expression, click its row in the Expression Manager table to select it, and then click Edit expression .

You cannot edit the results component, but you can edit the location, results options, complex options, and so on.

Add an expression

To add an expression, in the Expression Manager group, click Add Expression .

In the Multiple Reduction dialog box, you can quickly generate expressions for all loaded result components. Click Add All .
