hi,
i modeling multiphase model with VOF approach and transient physics in ansys fluent and results became stable.
now i want doing mesh independency.
which parameters is best for refining in mesh independency?
velocity, volume fraction or another?
or i must doing time step independency for this problem?
if answer to my question, i became happy.
thanks.

Hi
For mesh independence you should refine your mesh and compare parameters like Nusselt, Heat transfer Coefficient other parameters which you like, if the values are almost same so you achieved mesh independency otherwise you have to refine your mesh again till your values become almost same

Have you finished the mesh independency study? How is it ?
