I have problem with dam-break problem setting too!
 

Hi everybody,

I want to simulate dam-break problem in ansys-fluent, but I don't know how to define the water zone and how to separate it from air zone at initial condition. I would be thankful if somebody tell me what to do. I made a dambreak mesh in Gambit with 2 zones, the first zone for water and the 2nd for air. I defined the external boundary conditions, but about the interface between air and water I made it "interior". when I ran the setup in fluent nothing occured and water was still there, not falling.

PLEASE HELP ME ON THIS.

Thanks in advance.

here is the tutorial files involving the full settings in fluent and post processing data files for it click on the link below to see:

i don't use Gambit. but initializing your "ZONES" with water or air is done in FLUENT. and not in the pre-proccesing. Your need to have a normal grid. with two bodies -as they are called in ICEM- that's it. then in fluent you will associate the bodies with their materials... hope it can help
