please help me
i want to model vof model of lateral intake in U flum
it is .6depth that the water debpth is .15 m
i uceadaopt region and patch to patch the water zone
and seperate inlet to 2 part to set velocity inlet for water and air
but i ant recieve answer
please help

If you want help, please ask a clear question.

Nobody can understand what you mean. Try it like this:

i want to model 3D vof model in lateral intake of U flume
to do this,i have tried to model in gambit like picture
the depth of canal is 60 cm and water depth is 15 cm
in fluent i use adopt->region to creat to zone of water
then i tried initialize and then patch te region and volume fracton of water to 1.
and strat to iterate
but it does not seem to run good

This is the part that you need to be much more specific about.

Do you get error messages?
Does Fluent crash?
Do you get the wrong result?

We can not look into your computer, so if you want your problem to be solved you need to explain what your problem is.

tanx again
I get wrong results

[pakk]

Be more specific!
What is wrong about your results? Velocities? Densities? Temperature?
How do you know they are wrong? What are you comparing them to?

This is the last time I am going to ask you to be more specific, if you still failed to explain you problem in your next post, I give up.

I get wrong result in velocity
I creat surface in depth
that shoud show logarithm profile
but my result doesny shoe logarithm porofile and velocity in surface is less than in bottom

[Zaktatir]

????????

WHAT IS YOUR PROBLEM?

-Initialisation or not
-After Run bad Results or not?

[bahare]

I initialize that all variable to zero
and turbulence to 1
after run I get false result

[Zaktatir]

You have to share with us your model descirption and boundary condition etc..

[bahare]

I model u shape flum
velocity inlet for inlet
outflow for outlets
symmetry for top
i model one-phase
in my solve panel i use second order upwint and simple

[Zaktatir]

One Phase?

Which is the Top?

Why Outflow BC? DO you have fully-developed flow with normal zerfo-flux diffusion of all variables (expect the pressure)

[bahare]

top of the water
outfloe,because i have to instet the dishcharge ratio between to outlet
i dont get what u mean by zero flux difussion
