Hi!

I'm modeling a multiphase flow inside a thank (air/water)using laminaer and unsteady flow, dynmesh and the VOF model.

Does anyone know how I can locate the surface in general or close to the wall? I know that the volume fraction for each phase is availabele, but can't find it... any surgestions??

Thanks!

Hi!

Im not shure if that is what you want...To set the initial shape of water in the tank you have to go to Adapt-Region Adaption and Mark the region where you want the certain wolume fraction. Than go to Solve-Initialize-patch and set the desired volume fraction. The problem is that you can only determine shapes like lines, and circles in region adaption. This is also explained in VoF tutorial...

I hope i answered your question

Hi, I am assuling you want to follow the free interface air-water during after calculation using fluent (= height, or other parameter ... ). What I could suggest is to set an iso-surface at volume fraction in water or air = to 0.5. That is gonna help you to locate the free surface (= interface water-air). hope this help thomas
