Need help to show volume fraction in Fluent
 

Hi everybody!
I am modeling cavitation in pump, but when display the Contours/phase/ Volume fraction for vapor, i have picture like this( TK-xamthuc-thaydoiap-0.3-phahoi21.jpg).
But i saw some one who can show Vapor volume fraction as the picure image008.gif and image016.jpg.
So please help me how to do like that. Thank you very much

Hi,
You have plotted contours of volume fraction, whereas the pictures you want to produce are iso surfaces of volume fraction. to do that, you go to surface/iso-surfaces.
I hope this helps,
Marion.

Thank Marion,
I try to do that but it is still not working.

You should use iso-surfaces, The two photos have been taken using iso-surfaces.

Thank for your help! But I can not creat Iso-surface on my model.
Please help me!

Hi,
Why isn't it working?
Looking at your contour plot, I saw that you only have a max of 8.10E-5 for your volume fraction - that is very very small... Are you trying to create iso surfaces below this value?
Marion.

yes, I did it but it is still as this picture, I can not display bubble which is the same 2 picture I posted.

Hi,
When you create the iso-surface, DO NOT select a surface on the right hand side of the panel. That way it will create an iso surface for your domain, not on an existing surface (which I assume is what we see on your last picture)
