Input Parameters in Fluent Standalone

Hello,
I have always wondered what is the use of input parameter when Fluent stand alone( with no connection to Workbench) is used. It has the option of defining a parameter that can be done easily. However, how do you actually control the parameter value especially if you want to loop over that I/P parameter over multiple values ? Is there any way one can acess this defined parameter value in TUI ? For example, let's say that I want to see the effect of inlet flow velocities on a pipe of certain length. To ideally do this, I will define velocity inlet parameter in Fluent(standalone) and enter multiple values so Fluent solves for each individual value. How would I go forward with this ? One idea(rather a complicated one) is to acess the name of the defined I/P parameter. Once the name of the parameter or its ID has been acessed, it's value an be looped using a 'do' loop in Scheme. Something like this:- Code:
(do ((parameter start_value ( + parameter increment_value))) ((> x end_value)) (ti-menu-load-string ( format #f "set the parameter value" x)) ; HOW WOULD YOU THE SET THE VALUE (ti-menu-load-string (format #f"solve/iterate 10")) ;SOLVE THE SOLUTION WITH THE NEW PARAMETER VALUE ) |

In standalone Fluent, it's better to use the TUI commands rather that use the WB scripting language.
If you insist on using parameters you would update a parameter by using: Code:
/define/parameters/edit "nameofParameter" newValue Code:
/define/boundary-conditions velocity-inlet myInlet () vmag no 10 Last edited by LuckyTran; April 13, 2018 at 17:36. |

Yes. I was thinking the same. A while later I realized that there would not be much of a difference if I looped the BC settings or the parameter values. I will go with looping the parameters since that seems a much striaghtforward way to do. Also, the command for editing the I/P parameters is not long.
