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. |

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. |

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) Marion. |

I'm a beginner with CFD, Fluent, Multiphase & VOF. So please bear with me if my question is too obvious.
I am modeling a distributor, with 1 inlet & 4 outlets, trying to find the volume fraction of my 2nd phase & have been following the instructions I found here & in the manual. But somehow I ended up with this (attached pic) 2 distributors instead of one!!!! & the gradient of results is stuck in 3.5e-1 for all colors!! I don't know what I did wrong Please help me |
