Volume Fraction & Velocity Magnitude

alven299 · September 3, 2010, 10:32

Greeting to all CFD users,

I'm simulating a 3D system using FLUENT and currently facing problem in extracting certain data from it. Given the following:

Volume: 0.1 m3
max velocity magnitude: 1.7 m/s

Question:
How can I ask FLUENT to generate the percentage of volume which has velocity magnitude of less than 5% of the maximum velocity?

Thank you very much in advance for any suggestions and inputs.

I have managed to figure it out. First...use the iso-value adaptation to mark the region of desired velocity magnitude. Then separate the marked zone in grid>separate>cells. Finally, use the report volume and select the newly separated zone.
