Hi users,, I am working in CFX 5.6 in the pre window.I have fluid to fluid interface, but when I define the first domain as air and the second domain as water, the first domain will be changed automatically to water and vice versa. Why is that?? Thanx in advance

Hi, Zaher This happens because you don`t have any wall between different fluids. I think that if you don`t have any physical wall then you should setup multiphase simulation. If you define fluid-fluid interface without thin walls then your fluid automaticaly adjusted to have same physical models.

What you are trying to do (two seperate domains, two fluids) is only possible in CFD 5.7. Just ask for an beta version at your local representative.
