water simulation

hello world,

This is my first time of doing simulation with something else besides Air.

I want to simulate a water flow..is it possible in openfoam?

what parameters should i use? what tutorial should i use?
Any help would be highly welcome

cheers

Just go through tutorials in User Guide, everything is there.

Water is for almost all practical purposes incompressible (except if you are working with hydroacoustics), and you should choose some of the simpe, incompressible solvers in OF. That is icoFoam, pisoFoam, pimpleFoam and simpleFoam with friends. Then you set the kinematic viscosity to 1e-6 (approx. for fresh water) and you are good to go.

For free-surface simulations you should choose interFoam, but that is a complicated topic you should avoid if you are fresh in the game.
