Hi Dear all, I am using vof model with 2 phases .. my problem is writing a UDF which specify the varaition of the volume fraction of the prymary and/or secondary phase with time and space (say as a sinusoidal or gaussian varation law for example).. like a sinusoidal or a gaussian varaition of the Free interface between the 2 phase ...

when I try to use the C-VOF with this law , and introduce time ans spacial coordinates..I have error message..(Access violation..) can some body has deal with similar problem help me ...please!..any suggession ... thanks in advance

Dear Frederik,

I used the VOF method to simulate gas-liquid and liquid-liquid two-phase flow using my own fortran code since 1997.

Currently, I am also using the Fluent 6.2. You might forward me your UDF founction. I would like to find the bug for you.

Good luck!

Dear Sir,

You could use the VOF model and also use the translation reference frame. I simulated similar case in 1999 to 2000.

Good luck!

Dear Sir,

I finished the project at U of Toronto many years ago.

Sorry, The case file could not be found any more.

Good luck!
