TUI for zone fixed value

nenazarian · August 6, 2012, 13:43

Hi

Does anyone know how to fix only one value in cell zone condition?
I used this command:
define/boundary-conditions/fluid/(zone name)/fixed-value

but the problem is you cant only fix temperature and leave the rest unchanged. enabling "fixed value" option will set velocity and other parameters as fixed too...

any suggestion?

Cheers

You can turn on the fixed value in the cellzone conditions GUI. Then enter the value for the temperature and keep the remaining parameters as none.

I am doing that right now but the whole point is to change it to TUI.
TUI command doesnt give u the "none" option in the list.

You can do it this way:

Use Profile for X Velocity (m/s) fixed? [yes]
Use UDF Profile for X Velocity (m/s) fixed? [yes] no
do this for 3 components and specify temperature as you wish.

Thank you for your response

you are right.I tried this before but then it gives some error about the "profile" in initializing .. do you know how I can fix that too?

I appreciate your help

This is what I get for initializing:

/solve/initialize/hyb-initialization
Error: interpolate_profile_field: thread 23: profile "" does not exist.

I just got back from ANSYS

"This is a bug in FLUENT14.0 and is fixed in our next version FLUENT14.5, which will be released during Nov. time. .."
