Defining and Assigning Parameters to Input Variables using TUI

How can I define a parameter and assign it to an input variable using Ansys Fluent TUI (Text User Interface)?

In the latest versions, the parameters have to be defined using Named Expressions (with the appropriate units). Therefore, you will only be allowed to create parameters using the Named Expressions TUI menu: /define/named-expressions/

For example, to create a parameter for a gauge pressure on a pressure outlet boundary condition:

1) Create the Named Expression and define it as a parameter:

/define/named-expressions/add "my_gauge" definition "0[Pa]" parameter yes q

2) Assign the expression to the proper boundary condition:

/define/boundary-condition/pressure-outlet outlet yes no "my_gauge" .... (actual full command depends from the models activated)
