Calculate Data Variable from Expressions

Use the Calculate tool to define a derived variable as a function of existing variables.

  1. From the Post ribbon, click the Calculate tool.

    Figure 1.
    The Derived Data Calculator dialog opens.
  2. Click to add a variable.
  3. Define the name and expression.
    • Define the name without spaces so that it can be utilized in further expression definitions.
    • If using an existing variable with a space in its names, like “wall shear stress”, replace the spaces with “_”.
    • Expressions are defined in python syntax.
    Tip: Click / to import or export defined expressions.
Once derived variables are defined, they are available for contours and probes or integration
