Adding and editing expressions is done on the PSI Expressions Editor window.

The evaluation method is either an expression or a function. For expressions the expression text can be tested by entering it on the command line in Design whilst at a suitable component. The description is simply a text string to describe the expression.
Note:
The order in which the expressions are evaluated may be changed using the Up/Down
arrows on the side of the Pipe Stress Interface Settings window.
