Hi all, How can I specify velocity components (x-velocity, y-velocity ...) from a profile file in velocity-inlet BC, using text command.

Many Thanks

Hi

1) read case and data file 2) read profile

file>read-profile>

boundary-profile name[] "type your file name" 3) define the boundary conditions

define>boundary-conditions>velocity-inlet>

zone-idname [inlet]

velocity specification method:components[yes]

reference frame absolute [yes]

coordinate system cartesian X,Y,Z[yes]

Use profile for x-velocity [yes]

profile name []"type your file name"

data name [] "x-velocity"

Use profile for y-velocity [yes]

profile name []"type your file name"

data name [] "y-velocity"

Use profile for z-velocity [yes]

profile name []"type your file name"

data name [] "z-velocity"

Turbulent specification method K and Epsilon [yes]

Use profile for TKE [yes]

profile name []"type your file name"

data name [] "turb-kinetic-energy" and soon

Hopefully you can follow my instruction

Thanks Alex,

Actually, I'm using a scheme file, so everything is ok down to (in your message)

profile name [] "type your file name"

data name [] "x-velocity"

I have used this command

(profile-name "myprofilename")

there was no error-message, but Fluent seems to ignore this instruction, so should I define a command to set velocity components?

Hi

Have you try to read your profile throught the GUI?

It seems to me that something it is not right!!!

The profile name is the filename located in the directory from where you are launching Fluent. It mush have all the caracters that you write, for instante, my file name is "pkehv" without any extension, if you write a name with extension you have to write "pkehv.tex"

Anyway do it first throught the GUI and check if it can read it!! Also under define>profile> you can delete, list and read profiles

Hi,

it's Ok with a journal file, I first started with the GUI. Now, I'm trying to do the same thing every time step, but I don't know what's the procedure for achieving this work (UDF, Scheme file, ...). so, any suggestions are welcome

Hi

I have not working with scheme file. However, i suggest that you run this throught the bath mode or also calles background.
