I use the Ansys 13, and have several quastion as below.
First, when using coupled Level set with the VOF model, how i set the initial condition? is it ok for level set function to set zero in intialization?
second, is it possible to sovle the VOF+Level set with Solidification/melting model together?
Please give me advice.
Thanks

Did you solve the problem? Did you figure out how to set initial conditions of coupled level set and VOF method in Ansys?

Can you please help me.. I have same question .. How to initialize the level-set field ..i have defined the volume fraction correctly for my problem.

1- if I only use vof model. (explicit- geo-reconstruction) residual converges and simulation runs and I am getting results.

2- I have to run simulation with CLSVOF in FLUENT. when i select this option and keeping all other parameters same, my residual for ls-function does not change. I assume I have not initialized Level-set field as I did in my in-house code.

Please describe the method to initialize the level set field in fluent.

thanks
