I dont know if i understand the problem exactly, so iŽll repeat it in my own words: You have a Tank (better a t-valve), where u have 2 inlets (Inlet 1 = Hot Water / Inlet 2 = cold Water) and 1 Outlet (Water with mixing temperatur). If this configuration represents your proble, check: http://www.ansys.com/demoroom/swf/de...OneWayFSI.html (The whole Ansys-Demoroom gives a good overviwe what u can / canŽt do). Generally i think you should run a transient analysis to view how the two fluids are mixing into each other over time. I think in your example it is also necessary to add a particle trace (see CFX-Tutorial). I my Opinion one domain is enough if you do not want to simulate for example the heat transfer. But i really dont know if i got the problem right. Hope this may help you!

 April 13, 2009, 15:21 thanks alot .but vortex?!! #3 Senior Member     hamed Join Date: Apr 2009 Posts: 148 Rep Power: 10 thanks a lot for your favor and i really appreciate that , except inlet and outlet u got that right but u know what?i just need to study the TRANSMITTAL of water in a completely isolated tank and see how the vortex is going to happen .do i need to defin to phase or somthing to see the vortex in the surface of the tank?and do i need to defin the surface a free slip wall or an opening one?
