Dear Fluent User,
I am modeling cavitation in 3-D Nozzle. I try to plot cavity as in the picture below ( the cavity appare in the Nozzle hole). I tried to use Iso-surface but it not work as I expect. Could some one help me how to do that? Thank you very much! (Sorry I dont know hoe to add image in the forum) This is the image of my model http://img577.imageshack.us/img577/2517/3p2f.jpg And this is the example cavity plot which I want to do http://img29.imageshack.us/img29/1276/xmi6.jpg |

I don't understand: are you asking by which variable you want to the create the iso-plot?
You may create the isoplot by means of the void fraction and then using another variable for post-processing on the created surface |

I mean do you know how to use Iso-surface or onothe option in Fluent to plot the cavity structure as in picture I posted above? I used contour plot but it just show the position of cavity and we could not see the cavity struture(3D), also I tried to use Iso-surface as advice from anothe topic in Forum or in Fluent guid, but it still not work |

-1/Create a Surface by Iso-Value (Iso-Surface)
2/ Choose VOF as the variable of interest and give a reference Value 3/Then you have now a new surface which may be used for further post-processing By the why how high is the void fraction for your cavity (0,5?)? |

I dont kown what value should use, because the VOF value from 0.1 to 0.9
