Return a value from TUI

asal · March 2, 2016, 10:52

Hi!

How can I return a value from TUI? With a TUI command, I get a velocity in a point in my simulation domain and I want to set this value somewhere in my boundaries. Therefore, I need to return this value from TUI to be able to use it.
Any idea?!
thanks.

What do you mean?

The way I understand what you do:

You type a TUI command. For example:

Code:

(secretfunctiontogivevelocity)

The TUI responds by saying:

Code:

24.5119

You open the boundary condition you want to change, and type "24.5119" in the appropriate place.

Is this what you want, or is it what you want but you want it to be different?

Hello and thanks for your reply.

Let's assume that I got the temperature on point_1 by the following command:

Code:

report surface-integrals facet-avg point_1 , temp ,

and fluent report:

Code:

Now I want to take this value and assign it to the inlet boundary

Code:

define boundary-conditions inlet ,,,,,,,,, XX ,,

Above instead of XX, I need to read the previous return values (in this case 291) and substitute to XX. How can I return the reported value from the first command in order to use it later on as an input.
Hopefully it is clear now.
thanks.

OK, I understand. This is possible, I think, but you have to deal with annoying scheme-code.

To get a number from the TUI as variable, you can use pick-a-real.

Code:

(pick-a-real "report surface-integrals facet-avg point_1 , temp ,")

To send a command to the TUI, you can use ti-menu-load-string.

Code:

(ti-menu-load-string "define boundary-conditions inlet ,,,,,,,,, XX ,,")

Now, instead of XX, you want to put the number in the string. This can be done with format.

Code:

(format #f "define boundary-conditions inlet ,,,,,,,,, ~a ,," 300)

So, altogether:

Code:

(ti-menu-load-string (format #f "define boundary-conditions inlet ,,,,,,,,, ~a ,," (pick-a-real "report surface-integrals facet-avg point_1 , temp ,")))

I don't have Fluent open at the moment, so I did not test this.

Hello again and thanks a lot.
It works perfect.

Just one more question.
Is it possible to have if statement here in the Scheme?
thanks.
